Question

Fill in the blanks by choosing the appropriate word/words from those given in the brackets:
(increases, decreases, positive, efficient, 68, non-efficient, no $\alpha$-hydrogen, $\alpha$-hydrogen, negative, Rosenmund's, greater, Cannizzaro, 74, common-ion effect, lesser, buffer action, diamagnetic, paramagnetic)
Solubility of silver chloride ............... in the presence of sodium chloride because of ............... .

Answer 1

Solubility of silver chloride decreases in the presence of sodium chloride because of common-ion effect.
Sodium chloride is a strong electrolyte and completely dissociates in aqueous solution to provide chloride ions that are common to silver chloride. This shifts the equilibrium for dissociation of silver chloride towards left.
$AgCl\rightleftharpoons A{g}^{+}+C{l}^{-}$
$NaCl\to N{a}^{+}+C{l}^{-}$
