Which is the correct representation of the solubility product constant of $A{g_2}Cr{O_4}$

A

${[A{g^ + }]^2}\,[CrO_4^{ - 2}]$

B

$[A{g^ + }]\,\,[CrO_4^{ - 2}]$

C

$[2A{g^ + }]\,\,[CrO_4^{ - 2}]$

D

${[2A{g^ + }]^2}\,\,[CrO_4^{ - 2}]$

Solution

(a) $A{g_2}Cr{O_4}⇌[2A{g^ + }] + [CrO_4^{ – \, – }]$

Hence ${K_{sp}} = {[A{g^ + }]^2}\,\,[CrO_4^{ – \, – }]$
