Question

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

A. The attractive forces in a solute need to be broken.
B. The attractive forces in a solute must be increased.
C. The attractive forces in a solute must be greater than the attractive forces in the solvent.
D. The attractive forces in a solvent must be increased.

Answer 1

Answer: Option (A) is the correct answer.

Step-by-step explanation:

When a solute is dissolved in a solvent then in order to dissolve the solute it is necessary that attractive forces between the solute must be broken such that solute molecules can combine with solvent molecules.

By increasing temperature, pressure, surface area etc of a solution we can break the attractive forces between the solute.

Thus, we can conclude that in order for a solute to dissolve in a solvent it is true that the attractive forces in a solute need to be broken.

Answer 2

In order for a solute to dissolve in a solvent, the attractive forces in a solute need to be broken. So, the best option is A.
