The effect of temperature on the solubility of a salt is that

Solubility of the salt increases with an increase in temperature.

When the temperature rises, the kinetic energy of the molecules likewise rises, which causes solvent molecules to break solute molecules with intermolecular attraction. 

This allows the solute and solvent particles to combine easily to produce solutions. As we are aware, an endothermic reaction moves forward when the temperature increases. 

Additionally, the dissolution process for the majority of ionic substances is endothermic due to the positive change in enthalpy. As a result, solubility rises as temperature rises.
