Is "molarity" the same thing a "solubility"?

Jun 5, 2016

No, solubility and molarity are two different properties.

Explanation:

Molarity is a measure of concentration, i.e. $\text{Number of moles"/"Volume of solution}$. Its units are thus $m o l \cdot {L}^{-} 1$.

Solubility is typically defined as the ability of a substance (gas, liquid, or solid) to dissolve in a solvent (typically a liquid).

It can thus have diverse units:

$\text{Amount of solute"/"Volume of solution}$, i.e. $m o l \cdot {L}^{-} 1 , g \cdot {L}^{-} 1$, $m g \cdot {L}^{-} 1 = \text{ppm}$

A $\text{saturated solution}$ is a solution whose concentration is equal to the concentration it would have if the solution were in equilibrium with undissolved solute.
