B) Solubility always increases as temperature increases.
C) Solubility usually decreases as temperature increases.
D) Solubility usually increases as temperature increases.

Question

Quizplus · Accepted Answer

In most cases, solubility increases as temperature increases for liquids and solids. This is due to the fact that increasing temperature usually means higher kinetic energy, which allows for greater molecular movement and collisions between the solute and solvent molecules, increasing the chance for solute dissolving in the solvent. However, there are some exceptions where solubility may decrease with increased temperature, such as when chemical reactions occur or when a decrease in temperature causes a shift in the equilibrium between the solute and solvent. But overall, the general trend is that solubility increases with temperature for liquids and solids.
