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 this 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 correct statement that summarizes the general relationship between solubility and temperature for most solutes (except for Ce2(SO4)3) is:

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

In general, for most solid solutes, increasing the temperature results in higher solubility due to increased kinetic energy, which helps break the bonds in the solute and allows it to dissolve more readily in the solvent.
