It looks like you've uploaded a worksheet titled
"Solutions, Solutes and Solvents" that asks students to identify the
solute,
solvent, and
solution in various mixtures. Below is a
step-by-step explanation of how to solve this worksheet, along with the
correct answers.
---
🔍 Understanding Key Terms:
-
Solution: A homogeneous mixture of two or more substances.
-
Solute: The substance that dissolves (usually present in smaller amount).
-
Solvent: The substance that does the dissolving (usually present in larger amount). It’s often a liquid.
> 💡
Tip: In most cases, the solvent is the component in greater quantity or the one that "does the dissolving."

✔ Let's go through each example:
| Mixture | Solution | Solute | Solvent |
|--------|---------|--------|--------|
| 1.
Saltwater | Saltwater | Salt | Water |
| 2.
Milk made with sugar and water | Milk (sweetened) | Sugar | Water |
| 3.
Kool-Aid made with fruit drink mix and water | Kool-Aid | Fruit drink mix | Water |
| 4.
Acetic acid mixed with water (vinegar) | Vinegar | Acetic acid | Water |
| 5.
Vinegar mixed with alcohol and water | Vinegar-alcohol solution | Alcohol | Vinegar (or water, depending on context) |
| 6.
Tea made with tea leaves and water | Tea | Tea leaves | Water |
> ⚠️ Note: For #5, it's a bit ambiguous because vinegar is already a solution (acetic acid + water). If you're adding alcohol to vinegar, then:
> -
Solute: Alcohol
> -
Solvent: Vinegar (which itself is mostly water and acetic acid)
But if we consider vinegar as the
main liquid base, it acts as the
solvent for alcohol.

📝 Final Answer Table:
| Mixture | Solution | Solute | Solvent |
|--------|---------|--------|--------|
| 1. Saltwater | Saltwater | Salt | Water |
| 2. Milk made with sugar and water | Sweetened milk | Sugar | Water |
| 3. Kool-Aid made with fruit drink mix and water | Kool-Aid | Fruit drink mix | Water |
| 4. Acetic acid mixed with water (vinegar) | Vinegar | Acetic acid | Water |
| 5. Vinegar mixed with alcohol and water | Vinegar-alcohol solution | Alcohol | Vinegar |
| 6. Tea made with tea leaves and water | Tea | Tea leaves | Water |

🧠 Explanation of Each:
1.
Saltwater: Salt dissolves in water → salt = solute, water = solvent.
2.
Milk + sugar + water: Sugar dissolves in water; milk is just flavoring but not dissolved in the same way → sugar is solute, water is solvent.
3.
Kool-Aid: Powdered mix dissolves in water → mix = solute, water = solvent.
4.
Vinegar: Acetic acid dissolved in water → acetic acid = solute, water = solvent.
5.
Vinegar + alcohol: Alcohol is added to vinegar → alcohol = solute, vinegar = solvent (since it's the bulk liquid).
6.
Tea: Tea leaves steep in hot water, releasing compounds → tea leaves are source of solutes, water is solvent.
---
✔ Summary:
- Always ask: “What is dissolving?” → That’s the
solute.
- “What is doing the dissolving?” → That’s the
solvent.
- The final mixture is the
solution.
