# What describes the quantity of solute that can dissolve in a given amount of solvent at a given temperature?

$\text{The intrinsic solubility of the solute..........}$
Solubilities are often quoted in $g \cdot {L}^{-} 1$; sometimes, for sparingly soluble salts, ${K}_{\text{sp}}$ values are quoted, the $\text{solubility-product}$, an equilibrium constant that relates the ion product to a constant at a given temperature.
