Question

In order for a solute to dissolve in a solvent, what must be true?

Answer 1

(1) The attractive forces in a solute need to be broken. (2) The attractive forces in a solute must be decreased. (3) The attractive forces in the solute must be greater than the attractive forces in the solvent. (4) The attractive forces in a solvent must be increased.

Answer 2

Answer:

• In order for a solute to dissolve in a solvent, the attractive forces must be broken.

Explanation:

The rule of solubility says

                                    "Like dissolve Like"

There should be following process in order to dissolve solute into solvent

(1). The particles of solute should be apart.

(2). The solvent particles should move apart to extent so that solute particles should entrapped between solvent particles

(3).  The particles of solute and solvent should attract to each others so that they can mix.

Summary:

• If new forces arises between the solute and solvent dominate over the forces between the particles of solute, then solute become dissolve into solvent and vice versa.
