Question

Why does the solubility of a solute decrease with an increase in temperature?

Answer 1

Solubility:

• A homogenous combination of one or more solutes in a solvent is referred to as a solution.
• A typical illustration of a solution is the addition of sugar cubes to a cup of tea or coffee.
• Solubility is a quality that aids in the dissolution of sugar molecules.
• Thus, the ability of a material (solute) to dissolve in a certain solvent may be characterized as solubility.
• Any material that is dissolved in a solvent and is either solid, liquid, or gas is referred to as a solute.

Effect on solubility if the temperature increases:

• The solute's solubility falls because the kinetic energy of the gaseous solute increases as the temperature rises.
• As a result, its molecules are more likely to escape the solvent molecule's attraction and return to the gas phase.
