Question

At a certain temperature, the solubility of the salt, $ M_mA_n $ in water is $ s\, mol/L $ . The solubility product of the salt is

• A. $ M^m A^n $
• B. $ (m+n)S^{m+n} $
• C. $ m^m n^n s^{m+n} $
• D. $ m^m A^n s $

Answer 1

Answer: (C)

$M_{m} A_{n}(s) \longrightarrow \underset{ms}{m M^{n+}}+\underset{ns}{n A^{m+}}$

$K_{s p} =\left[M^{n+}\right]^{m}\left[A^{m+}\right]^{n}$

$=(m s)^{m}(n s)^{n}$

$=m^{m} n^{n}(s)^{m +n}$
