Question

State whether the given statement is true or false:

$AgCl$ is less soluble in aqueous sodium chloride solution than in pure water.

• A. True
• B. False

Answer 1

The correct option is A True

$AgCl\rightleftharpoons A{g}^{+}+C{l}^{-}$
$NaCl\to N{a}^{+}+C{l}^{-}$

Sodium chloride is a strong electrolyte and is completely dissociated. This increases the chloride ion concentration in solution and suppresses the ionization of AgCl. Hence, the solubility of AgCl decreases.
