Which option best defines solubility?

• A. The rate at which a solute dissolves.
• B. The color of the resulting solution.
• C. The amount of solute that can dissolve in a solvent at a given temperature.
• D. The density of the solvent.

Answer: (C)

Solubility is about how much of a solute the solvent can hold in dissolved form at a specific temperature. It refers to the maximum amount that can dissolve before the solution becomes saturated, not how quickly the solute dissolves. This is why the option describing the quantity of solute that can dissolve at a given temperature best defines solubility. The color of the solution and the density of the solvent are separate properties and don’t define how much solute can be dissolved. Solubility can be expressed in units like grams of solute per 100 grams of solvent or per liter of solution, and it often changes with temperature. For example, more sugar can dissolve in hot water than in cold water, illustrating how temperature affects solubility.
