Question

Explain the effect of temperature on solubility of solid in liquid. Write an equation of Van't Hoff factor for abnormal molecular weight. How is it affected by association and dissociation?

Answer 1

Answer:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
