Solution

The correct option is D $M X > M_{3} X > M X_{2}$
$M X : K_{s p} = S^{2} = 4 \times 10^{- 8}$
$\Rightarrow S = 2 \times 10^{- 4}$

$M X_{2} : K_{s p} = 4 s^{3} = 3.2 \times 10^{- 14}$
$\Rightarrow S = 2 \times 10^{- 5}$

$M_{3} X : K_{s p} = 27 s^{4} = 2.7 \times 10^{- 15}$
$\Rightarrow S = 10^{- 4}$
Hence, order of solubility is $M X > M_{3} X > M X_{2}$

Solubility product constant (Ksp) of salts of types MX,MX2 and M3X at temperature 'T' are 4.0×10−8,3.2×10−14 and 2.7×10−15 respectively. The solubilities (mol/dm^3) of the salts at temperature 'T' are in the order:

The correct option is D MX>M3X>MX2MX:Ksp=S2=4×10−8 ⇒S=2×10−4 MX2:Ksp=4s3=3.2×10−14 ⇒S=2×10−5 M3X:Ksp=27s4=2.7×10−15 ⇒S=10−4 Hence, order of solubility is MX>M3X>MX2
