Answer to Question #110745 in General Chemistry for yulissa

Question

what will NOT increase the solubility of a solid solute, such as KCl, in water?

Answer 1

The best way to determine the solubility of solid is by experiment.

While it is difficult to predict the solubility of solids, however there some correlation between the solubility of a solute and Δ

, that's why we can discuss the depends on temperature as follows.

The solubility of solutes in solvents could be increased or decreased by increasing or decreasing temperature, this depends if the dissolution of the substrate is exothermic or endothermic.

Exothermic dissolution : The increase in temperature will decrease the solubility.

Think "Le Châtelier's Principle".

When heat is added the equilibrium will shift to the left which will decrease the solubility.

Endothermic dissolution: The increase in temperature will increase the dissolution.
