Educational worksheet on solutions, solvents, and solutes, including a crossword puzzle and table completion exercises.

Let's solve the "SOLUTION, SOLVENT AND SOLUTE WORKSHEET" step by step.

1. FIND THE MISSING LETTERS

#### a) Separation method used for solutions - E__ P__ A__ ION

We are looking for a separation method commonly used for solutions, especially when separating solute from solvent.

The most common method is Evaporation.

So:
E V A P O R A T I O N

✔ Answer: EVAPORATION

> ✔ *Explanation:* Evaporation is used to separate a soluble solid (like salt) from a liquid (like water) in a solution.

---

#### b) Separation method used for insoluble solutions - __DI__ __TA T I __N and D__ C__ __AT __ ON

We’re looking for two methods used to separate insoluble mixtures.

- First one: FILTRATION
→ The clue has “__DI__ __TA T I __N” — this fits FILTRATION
(F-I-L-T-R-A-T-I-O-N)

- Second one: DECANTATION
→ "D__ C__ __AT __ ON" → D-E-C-A-N-T-A-T-I-O-N

✔ Answers:
- FILTRATION
- DECANTATION

> ✔ *Explanation:*
> - Filtration separates solids from liquids when the solid doesn't dissolve (e.g., sand and water).
> - Decantation is used to pour off the liquid from a mixture where solid has settled at the bottom.

2. COMPLETE THE FOLLOWING TABLE

| SOLUTE | SOLVENT | SOLUBLE/INSOLUBLE SOLUTION |
|---------------------|-------------|----------------------------|
| Chocolate | Milk | Chocolate Milk |
| Chalk | Water | Insoluble |
| Oxygen, Hydrogen | Nitrogen | Soluble |
| Coffee powder | Water | Coffee |
| Sand | Water | Sand and Water |
| Sugar | Tea | Sweet Tea |

#### Let's fill each row:

1. Chocolate + Milk → Chocolate Milk
→ Solute = Chocolate, Solvent = Milk → Already filled.

2. Chalk + Water → ?
→ Chalk (calcium carbonate) does not dissolve in water.
→ So it’s an insoluble solution.

3. Oxygen, Hydrogen + Nitrogen → ?
→ Gases like oxygen and hydrogen can dissolve in nitrogen (in air), so they form a soluble gas mixture.
→ This is a soluble solution (gas in gas).

4. Coffee powder + ? → Coffee
→ Coffee is made by dissolving coffee powder in water.
→ So solvent = Water

5. ? + Water → Sand and Water
→ Sand does not dissolve in water.
→ Solute = Sand

6. ? + Tea → Sweet Tea
→ Sweet tea gets sweetness from sugar dissolved in tea.
→ Solute = Sugar

✔ Final Table:

| SOLUTE | SOLVENT | SOLUBLE/INSOLUBLE SOLUTION |
|---------------------|-------------|----------------------------|
| Chocolate | Milk | Chocolate Milk |
| Chalk | Water | Insoluble |
| Oxygen, Hydrogen | Nitrogen | Soluble |
| Coffee powder | Water | Coffee |
| Sand | Water | Sand and Water |
| Sugar | Tea | Sweet Tea |

3. CROSSWORD PUZZLE

Let’s solve the clues.

#### Across:

4. Is a type of substances.
→ This refers to SOLUTE, SOLVENT, or SOLUTION. But given context, likely SOLUTE or SOLUTION.
But look at Down 8: "Is a part of solution." → That’s SOLUTE or SOLVENT.
But clue 4 says “a type of substances” — could be SOLUTION?

Wait — let's check possible answers based on grid.

Let’s analyze the structure.

From the clues:

---

#### Down Clues:

1. Used as solute in honey water.
→ Honey is dissolved in water → Solute is Honey

2. Method for separating insoluble solution.
→ FILTRATION (from earlier)

3. Is a solution. (coffee/chalk and water)
→ Could be COFFEE or CHALK AND WATER → but likely COFFEE (as it's a common example)

6. Is an insoluble solution. (oil/tea)
→ Oil and water don’t mix → OIL AND WATER or just OIL
But “solution” here means mixture → probably OIL or OIL-WATER

7. Can be separated by Sedimentation and Decantation.
→ This applies to SAND AND WATER or any insoluble solid-liquid mixture → e.g., SAND AND WATER

8. Is a part of solution.
→ Either SOLUTE or SOLVENT

---

Now, let’s try to fit them.

Let’s assume the crossword looks like this (based on standard format):

```
1
|
|
4 | 3
|
|
5
|
6
|
|
|
8
|
|
7
```

But better to use logic.

Let’s start with Down 1: Used as solute in honey water → HONEY

So Down 1 = HONEY → 5 letters.

That must be a vertical word of 5 letters.

Similarly, Down 2: Method for separating insoluble solution → FILTRATION → 10 letters? Too long.

Wait — maybe shorter.

Wait: Is there a shorter method?

Filtration is 10 letters — unlikely.

Maybe FILTERING? Still long.

Wait — perhaps FILTRATION is across?

But Down 2: Method... → could be FILTRATION if it’s long.

But let's see.

Wait — perhaps FILTRATION is Across?

No — clue says "Down".

Let’s reconsider.

Wait — maybe the method is DECANTATION or SEDIMENTATION?

But clue 2: Method for separating insoluble solution → FILTRATION is correct.

But length?

Let’s suppose the grid allows 10 letters.

Alternatively, maybe it's FILTERING or FILTRATE — no.

Wait — perhaps it's FILTRATION — we’ll go with that.

But let’s try to find shorter words.

Wait — maybe the answer is FILTRATION, and it's a long down word.

Let’s assume:

- Down 1: HONEY (5 letters)
- Down 2: FILTRATION (10 letters) → very long
- Down 3: ? → "Is a solution" → COFFEE (6 letters) or CHALK AND WATER → too long
- Down 6: "Is an insoluble solution" → OIL AND WATER → too long; maybe just OIL?
- Down 7: "Can be separated by Sedimentation and Decantation" → SAND AND WATER → 12 letters? No.

Wait — perhaps these are short words.

Let’s re-analyze.

Maybe the clues are designed with short answers.

Try:

#### Down 1: Used as solute in honey water → HONEY → 5 letters → OK

#### Down 2: Method for separating insoluble solution → FILTRATION → 10 letters → too long?

But wait — maybe it's FILTERING? Still long.

Alternatively, FILTRATION is acceptable.

But let’s see if we can find shorter ones.

Wait — perhaps FILTRATION is Across?

No — clue says "Down".

Wait — maybe the answer is FILTRATION and it's 10 letters — so it must be a long column.

But without the actual grid size, let’s assume standard.

Alternative idea: Perhaps the answer is FILTRATION and it's split.

Wait — maybe it's FILTRATION — we’ll go with that.

But let’s try solving with known answers.

Let’s list likely answers:

- Down 1: HONEY (5 letters)
- Down 2: FILTRATION (10 letters)
- Down 3: COFFEE (6 letters) — "is a solution"
- Down 6: OIL (3 letters) — "an insoluble solution" → oil and water → oil is the key substance
- Down 7: SAND AND WATER → too long; maybe SAND? But clue says “can be separated…” → so it’s the mixture → maybe SANDWATER? Not real.

Wait — perhaps SAND AND WATER is too long — maybe SAND or MIXTURE?

Wait — another possibility: SAND is the solute, but clue says “can be separated by sedimentation and decantation” → refers to the mixture.

So maybe SAND AND WATER → but how to write in crossword?

Perhaps the answer is SAND or SANDWATER?

But more likely: SAND AND WATER is too long.

Wait — perhaps the answer is SAND → but not accurate.

Another idea: SUSPENSION? Because sand and water form a suspension.

And suspensions can be separated by sedimentation and decantation.

So Down 7: SUSPENSION → 10 letters.

But clue: “Can be separated by Sedimentation and Decantation.” → yes, suspensions.

So SUSPENSION fits.

Similarly, Down 6: “Is an insoluble solution” → oil and water → forms an EMULSION or IMMISCIBLE MIXTURE, but not really a solution.

But “insoluble solution” is a misnomer — it's a mixture.

But clue says “is an insoluble solution” — likely means immiscible mixture.

But best term: OIL AND WATER → too long.

Or OIL?

Wait — perhaps OIL is the solute? But oil doesn't dissolve.

Wait — perhaps the answer is OIL.

But let’s go back.

Let’s look at Across:

4. Is a type of substances.
→ This could be SOLUTE, SOLVENT, or SOLUTION.

But clue says “a type of substances” — plural — so maybe SOLUTIONS?

But more likely: SOLUTE or SOLVENT.

But look at Down 8: “Is a part of solution.” → clearly SOLUTE or SOLVENT

So Across 4: “Is a type of substances” — could be SOLUTE, SOLVENT, or SOLUTION

But likely SOLUTION.

But “type of substances” — ambiguous.

Wait — perhaps it’s MIXTURE?

But clue says “substances” — so maybe SOLUTE, SOLVENT, SOLUTION are types.

But let’s try:

Across 4: SOLUTION → 8 letters

Across 5: Does not dissolve in water → INSOLUBLE → 9 letters

Across 8: Is a part of solution → SOLUTE or SOLVENT → 6 letters

Now let’s try to build.

Assume:

- Across 5: INSOLUBLE (9 letters) → must be a long horizontal word.
- Across 4: SOLUTION (8 letters)
- Across 8: SOLUTE or SOLVENT → 6 letters

Now Down:

1. HONEY (5 letters) → vertical
2. FILTRATION (10 letters) → very long
3. COFFEE (6 letters)
6. OIL (3 letters)
7. SUSPENSION (10 letters)
8. ??? → part of solution → SOLUTE or SOLVENT

Now, notice that Across 8 intersects with Down 8.

Let’s suppose:

- Down 8: SOLUTE → 6 letters
- Across 8: ??? → must be same letter at intersection

But Across 8 is “Is a part of solution” → also could be SOLVENT

But likely SOLUTE

Now, Across 4: “Is a type of substances” → likely SOLUTION or SOLUTE

But if Across 4 is SOLUTION, then it's 8 letters.

But Down 1: HONEY → starts at top → so Down 1 goes down from square 1.

Let’s sketch a minimal grid.

Assume:

- Down 1: HONEY (5 letters) → positions 1–5
- Down 2: FILTRATION → 10 letters → needs space
- Down 3: COFFEE → 6 letters
- Down 6: OIL → 3 letters
- Down 7: SUSPENSION → 10 letters
- Down 8: SOLUTE → 6 letters

Now Across:

- Across 4: ??? → intersects Down 1 and Down 2
- Across 5: INSOLUBLE → 9 letters
- Across 8: ??? → intersects Down 8

Now, Across 5: INSOLUBLE → 9 letters → likely spans from position 4 to 12 or so.

But let’s try to assign.

Perhaps:

- Across 4: SOLUTE → but clue says “is a type of substances” → not perfect.

Wait — perhaps SOLUTION is Across 4.

Let’s try:

- Across 4: SOLUTION (8 letters)
- Then Down 1: HONEY → starts at 1 → so Down 1 is H-O-N-E-Y
- Down 2: FILTRATION → F-I-L-T-R-A-T-I-O-N → 10 letters
- Down 3: COFFEE → C-O-F-F-E-E → 6 letters
- Down 6: OIL → O-I-L → 3 letters
- Down 7: SUSPENSION → S-U-S-P-E-N-S-I-O-N → 10 letters
- Down 8: SOLUTE → S-O-L-U-T-E → 6 letters

Now Across 5: Does not dissolve in water → INSOLUBLE → 9 letters

Across 8: Is a part of solution → SOLUTE or SOLVENT → but already used?

Wait — Across 8: must intersect with Down 8.

If Down 8 is SOLUTE, then Across 8 must have first letter S.

So Across 8 starts with S.

But what is Across 8? “Is a part of solution” → could be SOLUTE, but that’s 6 letters.

But Across 8 is horizontal — so if it's 6 letters, and Down 8 is vertical, then it shares the first letter.

But if Across 8 is SOLUTE, then it's the same as Down 8.

But usually crosswords don’t do that.

Unless it's the same word.

But clue says “Is a part of solution” — so both SOLUTE and SOLVENT are parts.

But only one can be chosen.

But perhaps Across 8 is SOLUTE.

Then Down 8 would be SOLUTE — same word.

But that’s possible.

But let’s see:

- Across 8: SOLUTE → 6 letters
- Down 8: SOLUTE → 6 letters → shared

But clue for Across 8: “Is a part of solution” → YES

Clue for Down 8: “Is a part of solution” → YES

But they are the same clue? No — different clues.

Wait — Down 8 is “Is a part of solution” → same as Across 8?

No — the clues are:

- Across 8: “Is a part of solution.”
- Down 8: “Is a part of solution.”

Same clue? Wait — no:

Looking back:

> Across
> 4. Is a type of substances.
> 5. Does not dissolve in water.
> 8. Is a part of solution.

> Down
> 1. Used as solute in honey water.
> 2. Method for separating insoluble solution.
> 3. Is a solution. (coffee/chalk and water)
> 6. Is an insoluble solution. (oil/tea)
> 7. Can be separated by Sedimentation and Decantation.
> 8. Is a part of solution.

Oh! Both Across 8 and Down 8 have the same clue: “Is a part of solution.”

So likely, the word is SOLUTE or SOLVENT.

But in a crossword, it’s possible.

But typically, it’s SOLUTE.

So let’s say:

- Across 8: SOLUTE
- Down 8: SOLUTE

But then the word is the same — possible.

But now, Across 5: “Does not dissolve in water” → INSOLUBLE → 9 letters

So Across 5 must be 9 letters.

Similarly, Across 4: “Is a type of substances” → could be SOLUTION → 8 letters

But let’s try to assign.

Assume:

- Across 4: SOLUTION (8 letters)
- Across 5: INSOLUBLE (9 letters)
- Across 8: SOLUTE (6 letters)

Now Down:

- Down 1: HONEY (5 letters)
- Down 2: FILTRATION (10 letters)
- Down 3: COFFEE (6 letters)
- Down 6: OIL (3 letters)
- Down 7: SUSPENSION (10 letters)
- Down 8: SOLUTE (6 letters)

Now, check intersections.

Suppose:

- Down 1: HONEY → occupies squares 1,2,3,4,5 vertically
- Down 2: FILTRATION → starts at 2, goes down 10 letters → so must be long column
- Down 3: COFFEE → 6 letters → starts at 3, goes down
- Down 6: OIL → 3 letters → starts at 6
- Down 7: SUSPENSION → 10 letters → long
- Down 8: SOLUTE → 6 letters

Now Across 4: SOLUTION → 8 letters → must start at 4 horizontally

But Across 4 starts at 4, and goes right.

But Down 1 is HONEY → so square (1,1) is H, (2,1) is O, etc.

Now Across 4: SOLUTION → S-O-L-U-T-I-O-N → 8 letters

So it starts at square 4, goes to square 11.

But square 4,1 is part of Down 1 → H (from HONEY)

But Across 4 starts at 4 → so square (1,4) is S

But Down 1 is at column 1 → so column 1 has H,O,N,E,Y

Column 4 has S (from Across 4)

So no conflict.

Similarly, Across 5: INSOLUBLE → 9 letters → starts at 5 → I-N-S-O-L-U-B-L-E

But Across 5 is likely below Across 4.

But Across 4 is at row 1, Across 5 at row 2?

But let’s assume rows.

Let’s define:

- Row 1: Across 4: SOLUTION (8 letters) → positions 4 to 11
- Row 2: Across 5: INSOLUBLE (9 letters) → positions 5 to 13

But Down 1: HONEY → column 1, rows 1 to 5 → H,O,N,E,Y

Down 2: FILTRATION → column 2, rows 1 to 10 → F,I,L,T,R,A,T,I,O,N

Down 3: COFFEE → column 3, rows 1 to 6 → C,O,F,F,E,E

Down 6: OIL → column 6, rows 1 to 3 → O,I,L

Down 7: SUSPENSION → column 7, rows 1 to 10 → S,U,S,P,E,N,S,I,O,N

Down 8: SOLUTE → column 8, rows 1 to 6 → S,O,L,U,T,E

Now Across 8: SOLUTE → must be in row 8, but we have only up to row 10.

Wait — confusion.

Actually, the numbers are clues, not positions.

Better to ignore coordinates.

Let’s accept that the answers are:

Final Crossword Answers:

#### Across:
4. SOLUTION — “Is a type of substances.” (A solution is a type of mixture/substance)
5. INSOLUBLE — “Does not dissolve in water.”
8. SOLUTE — “Is a part of solution.”

#### Down:
1. HONEY — “Used as solute in honey water.”
2. FILTRATION — “Method for separating insoluble solution.”
3. COFFEE — “Is a solution.” (coffee is a solution)
6. OIL — “Is an insoluble solution.” (oil and water don’t mix)
7. SUSPENSION — “Can be separated by Sedimentation and Decantation.” (sand and water is a suspension)
8. SOLUTE — “Is a part of solution.” (same as Across 8)

But Across 8 and Down 8 are the same clue and same answer — acceptable.

Note: “Oil” is not a solution, but it’s part of an immiscible mixture.

“Suspension” is the correct term for sand and water.

So even though “insoluble solution” is incorrect terminology, it’s likely referring to suspension.

So we go with:
