Each of the solutions above use water as the solvent. For all of the solutions except Ce2(SO4)3, the relationship between solubility and temperature is the same. Which statement summarizes the relationship?

Question

When the water is at a lower temperature, kinetic energy is reduced, increasing solubility.
When the water is at a lower temperature, kinetic energy is increased, increasing solubility.
When the water is at a higher temperature, kinetic energy is increased, increasing solubility.
When the water is at a higher temperature, kinetic energy is reduced, increasing solubility.

Answer 1

The statement that summarizes the relationship for the solutions, except for Ce2(SO4)3, is:

When the water is at a higher temperature, kinetic energy is increased, increasing solubility.

This is because, in general, the solubility of most solids in water tends to increase with an increase in temperature due to higher kinetic energy, which allows solute particles to overcome the forces holding them in the solid state.
