# What must occur in order for a solution to form?

Jul 1, 2018

Well, $\text{solute-solute}$ bonds must break....

#### Explanation:

...and $\text{solvent-solute}$ bonds must form...

Typically, but not exclusively, we deal with a solid solute, and a liquid solvent..and for a solution to form the the $\text{solute-solvent bonds}$ MUST be more energetic than those between $\text{solute-solute}$ and $\text{solvent-solvent}$. Water, while it has STRONG $\text{solvent-solvent}$ bonds, also forms exceptionally strong bonds with MOST solutes...and thus water is a potent solvent.

On the other hand, we could deal with a gaseous solution, the air we breathe is one such...and because intermolecular distances are so great, and intermolecular forces WEAK as a consequence, such solutions are easy to form...

On the other, other hand, we could deal with $\text{solid-solid}$ solutions...and most $\text{alloys}$ are an example....
