Equilibrium Question 212

Question: The saturated solution of $ Ag_2SO_4 $ is $ 2.5\times {10^{-2}},M. $ Its solubility product $ (K _{sp}) $ is [NCERT 1980]

Options:

A) $ 62.5\times {10^{-6}} $

B) $ 6.25\times {10^{-4}} $

C) $ 15.625\times {10^{-6}} $

D) $ 3.125\times {10^{-6}} $

Show Answer

Answer:

Correct Answer: A

Solution:

$ K _{sp}=4s^{3}=4\times {{[2.5\times {10^{-2}}]}^{3}}=62.5\times {10^{-6}} $ .
