To an aqueous solution of `Ag_(2)CrO_(4)` above its own precipitate , `CrO_(4)^(2-)` ions are added in the form of solution. This results in

Options

A. increase in concentration of `Ag^(+)` ions
B. decrease in concentration of `Ag^(+)` ions
C. increase in the value of solubility product
D. decrease in the value of solubility product.

Answer

B

Explanation

Equilibrium in solution of sparingly soluble `Ag_(2)CrO_(4)`
`Ag_(2)CrO_(4) hArr 2 Ag^(+) +CrO_(4)^(2-)`
Additon of `CrO_(4)^(2-)` ions will push the equilibrium in backward direction.
