Question

A salt with general formula MX2 has solubility product 4× 10- 12 in water. The concentration of M2 + ions in the aqueous solution of the salt is (A) 2× 10- 6 M (B) 1× 10- 4 M (C) 1.6× 10- 4 M (D) 4× 10- 10 M

It is ternary electrolyte. ∴ Ks p=4S3 S=10- 4 M ∴ [M2 +]=10- 4M

Q. A salt with general formula $M X_{2}$ has solubility product $4 \times 1 0^{- 12}$ in water. The concentration of $M^{2 +}$ ions in the aqueous solution of the salt is

$2 \times 1 0^{- 6} M$

$1 \times 1 0^{- 4} M$

$1.6 \times 1 0^{- 4} M$

$4 \times 1 0^{- 10} M$

It is ternary electrolyte.
$∴ K_{s p} = 4 S^{3}$
$S = 1 0^{- 4} M$
$∴ [M^{2 +}] = 1 0^{- 4} M$
