Equilibrium Question 291
Question: $ K _{sp} $ of an electrolyte AB is $ 1\times {10^{-10}}. $
$ [{A^{+}}]={10^{-5}}M, $ which concentration of $ {B^{-}} $ will not give precipitate of AB [BHU 2003]
Options:
A) $ 5\times {10^{-6}} $
B) $ 1\times {10^{-5}} $
C) $ 2\times {10^{-5}} $
D) $ 5\times {10^{-5}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ K _{sp}> $ ionic product $ 1\times {10^{-10}}>5\times {10^{-11}} $
