If a solute is to be soluble in a given solvent, which step in the solution-making process must have a negative value for its energy?

Question

Quizplus · Accepted Answer

The formation of solvent/solute interactions must have a negative value for its energy in order for a solute to be soluble. This indicates that energy is released in the process, making it favorable for the solute to dissolve in the solvent. The physical separation of solvent and solute particles may involve gaining or losing energy, depending on whether the particles are attracted or repelled by each other, but it does not necessarily determine solubility.
