SATHEE: Equilibrium Question 206

Equilibrium Question 206

Question: The solubility product of silver sulphide is $3.2 \times 10^{- 11} .$ Its solubility at the experimental temperature is

Options:

A) $2 \times 10^{- 4}$ moles per litre

B) $6 \times 10^{- 6}$ moles per litre

C) $1.2 \times 10^{- 5}$ moles per litre

D) $8 \times 10^{- 4}$ moles per litre

Show Answer

Answer:

Correct Answer: A

Solution:

$A g_{2} S$ ⇌ $2 A g^{+} + S^{-}$

$K_{s p} = 4 S^{3}$

$S = \sqrt[3]{\frac{K_{s p}}{4}}$

$= \sqrt[3]{\frac{3.2 \times 10^{- 11}}{4}} = 2 \times 10^{- 6}$
