Q. At a certain temperature, the solubility of the salt, $M_{m} A_{n}$ in water is $s m o l / L$ . The solubility product of the salt is

$M^{m} A^{n}$

$(m + n) S^{m + n}$

$m^{m} n^{n} s^{m + n}$

$m^{m} A^{n} s$

$M_{m} A_{n} (s) ⟶ m s m M^{n +} + n s n A^{m +}$

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

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

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