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

Answer:

No, solubility and molarity are two different properties.

Explanation:

Molarity is a measure of concentration, i.e. #"Number of moles"/"Volume of solution"#. Its units are thus #mol*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:

#"Amount of solute"/"Volume of solution"#, i.e. #mol*L^-1, g*L^-1#, #mg*L^-1="ppm"#

A #"saturated solution"# is a solution whose concentration is equal to the concentration it would have if the solution were in equilibrium with undissolved solute.
