A₂X(s) $\rightleftharpoons$2A⁺(2s) + X^2-(s); $K_{sp}=4s^3$; $s={\left(\frac{K_{sp}}{4}\right)}^{1/3}$

AX(s) $\rightleftharpoons$ A⁺($s^{\prime }$) + X⁻($s^{\prime }$); $K_{sp}=s^{\prime 2}$; $s^{\prime }=\sqrt{K_{sp}}$

AX₃(s) $\rightleftharpoons$ A³⁺(s") + 3X⁻(s"); $K_{sp}=27(s^{\prime \prime }{)}^4$; $s^{\prime \prime }={\left(\frac{K_{sp}}{27}\right)}^{1/4}$
