Some facts#

If the substance $M_mX_x$ dissociates in the solution according to the reaction:

$M_mX_x \iff m M^{x+} + x X^{m-}$
then its solubility equilibrium is defined as below:

$K_{sp} = \left[\mathrm M^{x+}\right]^m \left[\mathrm X^{m-}\right]^x$

where:
- $K_{sp}$ - solubility quilibrium of substance,
- $\left[\mathrm M^{x+}\right]^m$ - molar concentration of $M^{x+}$ ions in saturated solution,
- $\left[\mathrm X^{m-}\right]^x$ - molar concentration of $X^{m+}$ ions in saturated solution.
The solubility equilibrium is measured for saturated solution.
The solubility equilibrium is specific for a given substance.
Alternative name for solubility equilibrium is solubility product constant.
The solubility equilibrium is varies depending on the temperature. Chemical tables most often give values for 298K (25°C).
If product of ion concentrations in real solution exceeds the value of solubility equilibrium then it forms the precipitate.
If we know the solubility equilibrium and dissociation reaction, then we can calculate molar solubility of substance:

$S = \sqrt[x+m]{\dfrac{K_{sp}}{x^{x} m^{m}}}$
where:
- $S$ - molar solubility of substance $M_mX_x$ ,
- $K_{sp}$ - solubility equilibrium,
- $x$ - stoichiometric coefficient determined by dissociation reaction (see above),
- $m$ - stoichiometric coefficient determined by dissociation reaction (see above).
