What needs to happen for a solute to dissolve in a particular solvent? a. the attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. b. the attractions between the solute and solvent molecules must be greater than the attractions between the solvent particles. c. the attractions between the solute and solvent molecules must be greater than the attractions between the solute particles. d. the attractions between the solute and solvent molecules must be less than the attractions keeping the solute together and the attractions keeping the solvent together.

The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. This needs to happen for a solute to dissolve in a particular solvent .

Option A

Explanation:

Solute means the substances which get dissolved by another one, Ex: salt. On the other hand, Solvent refers the substance which dissolves. Ex: Water. To get dissolved in solvent, the particles present in solute move away.

It is possible only when the attractive force between solute and solvent are greater than binding force of solute and solvent.  Separation and mixing up with solvent particles, in general, called as solvatation.
