Verified Solution • 2025–26 Session moderate

The solubility product of a salt having general formula MX₂, in water is: 4

\times

10^-12 . The concentration of M²⁺ ions in the aqueous solution of the salt is :

Accepted Answer

M X_{2} ⇌ \underset{s}{M^{2 +}} + \underset{2 s}{2 X^{-}}

Where

s

is the solubility of

M X_{2}

then

K_{s p} =

s \times {(2 s)}^{2}

=

4 s^{3}

;

\Rightarrow

4 \times 10^{- 12} = 4 s^{3};

\Rightarrow

s = 1 \times 10^{- 4}

[M^{2 +}] = s

= 1 \times 10^{- 4}
