MCQ
Solubility product is
- ✓The ionic product of an electrolyte in its saturated solution
- BThe product of the solubilities of the ions of the electrolyte
- CThe product of solubilities of the salts
- DThe product of the concentration of the ions
$A _a B _{b(s)} \rightleftharpoons a A _{(a q)}^{+}+b B _{(a q)}^{-}$
$K _c=\frac{\left. [A ^{+}\right]^a\left[ B ^{-}\right]^b}{\left[ A _a B _b\right]}$
$K _{ s p }=\left[ A ^{+}\right]^a\left[ B ^{-}\right]^b$
$K_{\text {sp }}$, called the solubility product constant.
