NEET Chemistry Solubility Product MCQ Question

Type: MCQ-numerical-Medium-Class 11

For the sparingly soluble salt AgCl, the solubility product constant KspK_{sp} is given as 1.8×10101.8 \times 10^{-10} at a certain temperature. What is the solubility of AgCl in mol/L in pure water at this temperature?

A

34×10534 \times 10^{-5}

B

8×1058 \times 10^{-5}

C

1×1051 \times 10^{-5}

D

5×1055 \times 10^{-5}

Correct Answer

Option A

Detailed Explanation

For a sparingly soluble salt like AgCl, the solubility ss is related to its solubility product constant KspK_{sp} by the equation Ksp=s2K_{sp} = s^2. Solving s2=1.8×1010s^2 = 1.8 \times 10^{-10} gives s=1.8×1010=1.34×105s = \sqrt{1.8 \times 10^{-10}} = 1.34 \times 10^{-5} M.
