Acids, Bases, and Salts Crossword - WordMint - Free Printable

Let’s solve this crossword step by step using the clues and standard chemistry knowledge.

We’ll go clue by clue, matching definitions to common terms in acids, bases, and salts.

---

Across:

5. “a logarithmic scale that measures the acidity or alkalinity of a solution on a scale of 1 to 14”
→ That’s pH. But wait — it says “scale”, so maybe just “PH”? Actually, the term is “pH scale”, but since it’s asking for the name of the scale, and it’s 2 letters? Wait — look at the grid: Across 5 has 7 boxes? Let me check the image layout mentally.

Actually, looking at typical crosswords like this:

Clue 5 across: “a logarithmic scale...” → The answer is PHSCALE? No — too long. Wait — actually, the standard term is just pH, but that’s 2 letters. Hmm.

Wait — let’s read carefully: “a logarithmic scale that measures... on a scale of 1 to 14” — that’s describing the pH scale, but perhaps they want the word ACIDITY? No.

Actually, rethinking: In many textbooks, the phrase used is “the pH scale”. But if we look at Down 2: “a logarithm of a solution’s hydrogen ion concentration” — that’s also pH.

So maybe Across 5 is PHSCALE? Too long.

Wait — perhaps I should list all answers first based on definition, then fit into grid.

Let’s do that.

Standard terms:

- Substance whose water solution conducts electricity → ELECTROLYTE (Down 1)
- Logarithm of H+ concentration → pH (Down 2)
- Reaction between acid and base → NEUTRALIZATION (Down 3)
- Produces H3O+ only → ACID (Down 4)
- Compound from water + H+ → HYDRONIUM (Down 6) — H3O+ is hydronium ion
- Measure of hydroxide ion concentration → pOH (Down 7)
- Hydrogen atom without electron → PROTON (Down 9)
- Product other than water in neutralization → SALT (Down 10)

Now Across:

5. Logarithmic scale measuring acidity/alkalinity 1–14 → This is the pH scale, but likely they want PH — but how many letters? Looking at grid: Across 5 starts at top left, goes down? Wait no — Across means horizontal.

Looking at the grid description:

Across 5: probably 2 letters? Because Down 1 is vertical starting at same spot? Not sure.

Alternative approach: Use known vocabulary.

Common crossword answers for these topics:

Across 5: “logarithmic scale...” → PH (but 2 letters). If grid shows more, maybe ACIDBASE? Unlikely.

Wait — perhaps it's LOGARITHMIC? No.

Another idea: Sometimes they say “the pH” as the scale. But let’s check clue 12: “measure of hydrogen ion concentration” → that’s also pH. So conflict?

No — clue 12 is “measure of hydrogen (hydronium) ion concentration” → that’s pH

Clue 5 is “logarithmic scale that measures...” → also pH

But you can’t have two same answers unless different lengths.

Perhaps clue 5 is SCALE? Too vague.

Wait — let’s look at Down 2: “a logarithm of a solution’s hydrogen ion concentration” → definitely pH

Then Across 5 might be something else.

Re-read clue 5: “a logarithmic scale that measures the acidity or alkalinity of a solution on a scale of 1 to 14”

The full term is “pH scale”, but if we take “pH” as the answer, it fits both 5 and 12? That can’t be.

Unless... clue 12 is “measure of...” which is pH, and clue 5 is “scale” which is also referred to as pH.

In many contexts, “pH” refers to both the measure and the scale.

But in crosswords, sometimes they use “PH” for 2-letter answer.

Let’s assume Across 5 is PH (2 letters), and see where it fits.

Similarly, Across 8: “concentration of a substance in moles per liter” → that’s MOLARITY (8 letters)

Across 11: “substance that undergoes color change to determine when reaction is complete” → INDICATOR (9 letters)

Across 12: “measure of hydrogen ion concentration” → pH again? Or ACIDITY? But acidity is not a measure, it’s a property.

Actually, the measure is pH

Across 13: “substance that produces OH- as only negative ions” → BASE (4 letters)? But “only negative ions” — yes, Arrhenius base.

But let’s list with letter counts from typical grids.

Since I don’t have exact grid box counts, I’ll rely on standard answers.

Let me compile:

Down:

1. conducts electric current in water → ELECTROLYTE (11 letters)

2. log of H+ concentration → pH (2 letters) — but usually written as PH in crosswords

3. acid + base reaction → NEUTRALIZATION (14 letters) — too long? Maybe NEUTRALISE? But US spelling is NEUTRALIZATION.

Wait — perhaps shorter: SALTWATER? No.

Standard term is NEUTRALIZATION

4. produces H3O+ only → ACID (4 letters)

6. compound from water + H+ → HYDRONIUM (9 letters) — H3O+ is hydronium ion

7. measure of OH- concentration → pOH (3 letters)

9. H atom without electron → PROTON (6 letters)

10. product other than water in neutralization → SALT (4 letters)

Across:

5. logarithmic scale 1-14 → PH (2 letters) — but let’s say it’s PHSCALE? Unlikely.

Perhaps it’s ALKALINITY? No.

Another thought: sometimes "pH" is accepted for the scale.

8. moles per liter → MOLARITY (8 letters)

11. color change substance → INDICATOR (9 letters)

12. measure of H+ concentration → pH (2 letters) — again

13. produces OH- only → BASE (4 letters) — but "as the only negative ions" — yes, Arrhenius base.

But there’s a problem: multiple clues point to pH.

Perhaps Across 5 is SCALE and Across 12 is PH, but clue 5 specifically says "logarithmic scale", so it must be pH-related.

Let’s think differently.

In some curricula, the scale is called the "pH scale", but the answer might be "PH".

For Down 2, "a logarithm" — that’s pH.

For Across 5, "a logarithmic scale" — also pH.

But in the grid, they might be placed such that one is vertical, one horizontal, sharing a letter.

Perhaps Across 5 is 7 letters: what 7-letter word describes the scale? "ACIDITY" is 7 letters, but it’s not the scale, it’s the property.

"ALKALINE" is 8.

I recall that in some puzzles, "PHMETRIC" but no.

Another idea: perhaps "LOGARITHM" but that’s not specific.

Let’s look for standard answers online or from memory.

Upon second thought, in many educational crosswords, for "logarithmic scale measuring acidity", the answer is simply PH.

And for "measure of hydrogen ion concentration", also PH.

But that would mean two entries are the same, which is possible if they intersect properly.

Perhaps Across 5 is PH and Across 12 is also PH, but that seems odd.

Clue 12: "a measure of the hydrogen (hydronium) ion concentration" — that’s pH.

Clue 5: "a logarithmic scale that measures..." — that’s the pH scale, so perhaps the answer is PHSCALE but that’s 8 letters.

Let’s count the boxes from the image description.

From the user's image description, although not visible, typically in such worksheets:

- Across 5: starts at top, goes right, probably 2 boxes (since Down 1 starts below it and is long)

Assume Across 5 is 2 letters: PH

Across 8: "concentration in moles per liter" → MOLARITY — 8 letters, so likely 8 boxes.

Across 11: "color change substance" → INDICATOR — 9 letters

Across 12: "measure of H+ concentration" → PH — 2 letters

Across 13: "produces OH- only" → BASE — 4 letters, but "as the only negative ions" — yes.

But "base" is 4 letters, and if the grid has 13 across with many boxes, perhaps it's ALKALI or something.

Arrhenius base is defined as producing OH- ions, so BASE is correct.

Now Down:

1. conducts electricity → ELECTROLYTE — 11 letters

2. log of H+ concentration → PH — 2 letters

3. acid-base reaction → NEUTRALIZATION — 14 letters, too long for most grids. Perhaps NEUTRALISE (10 letters) or REACT? No.

Standard term is NEUTRALIZATION, but maybe abbreviated.

Another possibility: SALTFORMATION? No.

I think it's NEUTRALIZATION, and the grid accommodates it.

4. produces H3O+ only → ACID — 4 letters

6. compound from water + H+ → HYDRONIUM — 9 letters

7. measure of OH- concentration → POH — 3 letters

9. H atom without electron → PROTON — 6 letters

10. product other than water → SALT — 4 letters

Now, let's try to fill in with confidence.

Also, note that in the French chart, it's "Echelle des pH", so pH is central.

Let me list final answers based on standard knowledge:

Across:
5. pH
8. MOLARITY
11. INDICATOR
12. pH
13. BASE

But having pH twice might be acceptable if the grid allows.

Perhaps Across 5 is "ACIDITY" but that doesn't fit "scale".

Another thought: sometimes "pH" is written as "PH" in uppercase for crosswords.

For Down 3, "the reaction between an acid and a base" — the product is salt and water, but the reaction is called NEUTRALIZATION.

Perhaps they want TITRATION? No, titration is the process, not the reaction.

I think NEUTRALIZATION is correct.

To resolve the pH issue, let's see clue 5 vs clue 12.

Clue 5: "a logarithmic scale" — this is the pH scale, so the answer could be "PHSCALE" but unlikely.

Perhaps it's "LOG" but no.

I recall that in some puzzles, for "scale of 1 to 14", the answer is "PH".

And for "measure of H+ concentration", also "PH".

So I'll go with that.

For Across 13: "a substance that produces hydroxide ions (OH-) as the only negative ions when dissolved in water" — this is the definition of an Arrhenius base, so BASE.

But "base" is 4 letters, and if the grid has more, perhaps ALKALINE but alkaline is adjective.

Or HYDROXIDE but that's the ion.

No, the substance is a base.

Perhaps CAUSTIC but not accurate.

I think BASE is correct.

Now for Down 7: "a measure of the hydroxide ion concentration" — that's pOH.

Down 9: "hydrogen atom without its electron" — proton.

Down 10: "product other than water" — salt.

Down 6: "compound formed by combination of water with H+" — hydronium ion, so HYDRONIUM.

Down 4: "produces H3O+ as only positive ions" — acid.

Down 1: "conducts electric current" — electrolyte.

Down 2: "logarithm of H+ concentration" — pH.

Down 3: "reaction between acid and base" — neutralization.

Now, to confirm, let's write the answers.

Final decision:

Across:
5. PH
8. MOLARITY
11. INDICATOR
12. PH
13. BASE

Down:
1. ELECTROLYTE
2. PH
3. NEUTRALIZATION
4. ACID
6. HYDRONIUM
7. POH
9. PROTON
10. SALT

But Down 2 and Across 5 and 12 are all PH — that might be intentional if they share letters.

In the grid, Down 2 might be vertical at position where Across 5 starts, so if Across 5 is PH (horizontal), Down 2 is PH (vertical), they share the 'P' or 'H'.

Similarly, Across 12 might be elsewhere.

For Across 13, if it's "BASE", 4 letters, but the clue says "a substance", and in context, it's fine.

Perhaps it's "ALKALI" but alkali is a type of base.

I think BASE is correct.

Another possibility for Across 13: "ARRHENIUS" but that's the scientist, not the substance.

No.

So I'll go with that.

But let's double-check clue 8: "concentration of a substance in moles per liter" — yes, molarity.

Clue 11: indicator — yes.

Now for the final answer, since it's a crossword, I need to provide the words for each number.

The user didn't specify to list them, but since it's "solve the problem", and the problem is to fill the crossword, I should provide the answers for each clue.

But the instruction says "Final Answer: [Provide only the final correct answer]"

What is the final answer? Probably the completed crossword, but since it's text, perhaps list the answers.

Maybe they want the key terms.

Given the format, I think I should output the answers for each clue.

But to follow the rule, perhaps box the main concepts.

Since it's a puzzle, the final answer is the set of words.

But for simplicity, I'll list them.

After careful consideration, here are the answers:

Across:
5. PH
8. MOLARITY
11. INDICATOR
12. PH
13. BASE

Down:
1. ELECTROLYTE
2. PH
3. NEUTRALIZATION
4. ACID
6. HYDRONIUM
7. POH
9. PROTON
10. SALT

Note: PH appears multiple times, which is consistent with the definitions.

For Down 3, "NEUTRALIZATION" might be long, but it's the correct term. Some grids might accept "NEUTRALISE" but in US English, it's with Z.

I think it's fine.

So for the Final Answer, since the task is to solve the crossword, I'll provide the answers in a list.

But the instruction says "Final Answer: [Provide only the final correct answer]", so perhaps just the key terms or the filled grid.

Since it's text-based, I'll state the answers.

To comply, I'll write the answers for each number.

Final Answer:
Across: 5. PH, 8. MOLARITY, 11. INDICATOR, 12. PH, 13. BASE
Down: 1. ELECTROLYTE, 2. PH, 3. NEUTRALIZATION, 4. ACID, 6. HYDRONIUM, 7. POH, 9. PROTON, 10. SALT

But to make it neat, perhaps:

The solutions are:
- Across 5: PH
- Across 8: MOLARITY
- Across 11: INDICATOR
- Across 12: PH
- Across 13: BASE
- Down 1: ELECTROLYTE
- Down 2: PH
- Down 3: NEUTRALIZATION
- Down 4: ACID
- Down 6: HYDRONIUM
- Down 7: POH
- Down 9: PROTON
- Down 10: SALT

Yes.
