Equilibrium Question 837

Question: A litre of solution is saturated with $ AgCl $ . To this solution if $ 1.0\times {10^{-4}} $ mole of solid $ NaCl $ is added, what will be the $ [ A{g^{+}} ] $ , assuming no volume change-

Options:

A) More

B) Less

C) Equal

D) Zero

Show Answer

Answer:

Correct Answer: B

Solution:

The dissociation of a weak electrolyte $ ( AgCl ) $ is suppressed on adding the strong electrolyte having a common ion $ ( C{l^{-}} ) $ , hence concentration of $ A{g^{+}} $ ion will be less.
