AThe mass of solute in a fixed mass of solid
BThe rate at which a solute dissolves in water
CThe highest concentration reachable under set conditions
DThe temperature at which a solid starts to dissolve
Answer & Solution
Correct answer: C. The highest concentration reachable under set conditions
1. Solubility measures how far a substance can be dissolved in a solvent.
2. It is stated as the maximum concentration reachable under stated conditions.
3. Substances with large solubilities are called soluble, and those with low solubilities insoluble.
4. Speed of dissolving is a rate, which is a separate idea from how much can dissolve.
