Answer:The tendency toward randomness drives the solution process. & The new solvent-solute intermolecular attractions must about the same as the solvent-solvent and solute-solute attractions.
Step-by-step explanation:
Increase in entropy is a major driving force in chemistry. The dissolution of particles in solvent increases the entropy of the solution hence is a driving force and an important factor that influences solubility. Secondly, the degree of solute-solvent interaction must be approximately the same as that of solute-solute and solvent-solvent interaction since like dissolves like and dissolution of a solute in a solvent depends on intermolecular interaction between solute and solvent.
