Question

How can the solubility of a substance be increased?

Answer 1

The solubility of a solute can be increased by the following ways:

1. Heating: The solubility of a solute increases on heating the solution. For example, more sugar can be dissolved in hot water than in cold water.
2. Stirring: Stirring will dissolve more solute in a solvent. Here is an example. Add sugar to water in two glasses. Letting one solution remain undisturbed, stir the other. More sugar dissolves in the glass that is stirred.
3. Solute in powdered form: Powdered solute dissolves more than the solute in crystal form. For example, crushed sugar dissolves more in water than sugar cubes.
