SATHEE: Equilibrium Question 304

Equilibrium Question 304

Question: The solubility product of $A s_{2} S_{3}$ is $2.8 \times 10^{- 72}$ . What is the solubility of $A s_{2} S_{3}$ [Pb. CET 2003]

Options:

A) $1.09 \times 10^{- 15} m o l e / l i t r e$

B) $1.72 \times 10^{- 15} m o l e / l i t r e$

C) $2.3 \times 10^{- 16} m o l e / l i t r e$

D) $1.65 \times 10^{- 36} m o l e / l i t r e$

Show Answer

Answer:

Correct Answer: A

Solution:

$K_{s p} = [A s^{3 +}] [S^{2 -}]$ , $S = \sqrt[5]{\frac{K_{s p}}{108}}$

$= \sqrt[5]{\frac{2.8 \times 10^{- 72}}{108}}$

$= 1.09 \times 10^{- 15}$
