A) \[{{[A{{g}^{+}}]}^{2}}\,[CrO_{4}^{-2}]\]
B) \[[A{{g}^{+}}]\,\,[CrO_{4}^{-2}]\]
C) \[[2A{{g}^{+}}]\,\,[CrO_{4}^{-2}]\]
D) \[{{[2A{{g}^{+}}]}^{2}}\,\,[CrO_{4}^{-2}]\]
Correct Answer: A
Solution :
\[A{{g}_{2}}Cr{{O}_{4}}\]⇌\[[2A{{g}^{+}}]+[CrO_{4}^{-\,-}]\] Hence \[{{K}_{sp}}={{[A{{g}^{+}}]}^{2}}\,\,[CrO_{4}^{-\,-}]\]You need to login to perform this action.
