Question

4. How does the solubility of a substance depend upon the temperature of the water? Explain.

Answer 1

• At a certain temperature, the maximum amount of solute that can dissolve in a known quantity of solvent is called its solubility.
• The solubility of a substance in water increases as the temperature rises.
• When the temperature is increased the kinetic energy gained by the molecules of solvents is used up to break the intermolecular interactions and move into the spaces between water molecules.
• Example- In hot water, more sugar will dissolve than in cold water.
