Answers and Explanations
1. B – Sugar is the solute (the substance being dissolved), water is the solvent.
2. C – Air is a gas solution (mainly nitrogen as solvent, oxygen as solute).
3. B – Salt in water is a classic solid-liquid solution.
4. B – Water is the solvent in seawater; salt and other minerals are solutes.
5. B – Oxygen dissolved in water is a gas solute in liquid solvent.
6. A – In carbonated drinks, carbon dioxide (gas) is the solute.
7. B – Alcohol in water is a liquid-liquid solution.
8. A – Brass is a solid-solid solution (copper + zinc).
9. B – Air is a gas-gas solution (oxygen dissolved in nitrogen).
10. C – Amalgam is a solid (e.g., silver) dissolved in mercury (liquid).
11. A – Acetic acid is the solute in vinegar (solvent = water).
12. E – The solvent depends on which component is in greater quantity.
13. D – In gas-gas solutions, the component in greater amount is the solvent.
14. E – All listed combinations are possible.
15. C – When two liquids mix in all proportions, they are said to be miscible.
16. A – Hydrogen in palladium is gas solute in solid solvent.
