Physical and chemical equilibrium can respond to a change in their pressure, temperature, and concentration of reactants and products. To describe the change in the equilibrium we have a principle named Le Chatelier principle. According to this principle, even if we make some changes in equilibrium, then also the system even re-establishes the equilibrium by undoing the effect.
If we add `SO_(4)^(2-)` ion to a saturated solution of `Ag_(2)SO_(4)`, it will result in a//an

Options

A. Result in an increase in `Ag^(o+)` concentration
B. Result in a decrease in `Ag^(o+)` concentration
C. Shift `Ag^(o+)` ions from solid `Ag_(2)CrO_(4)` into solution.
D. Result in a decrease the `CrO_(4)^(2-)` ion concentration in the solution.

Answer

B

Explanation

Due to common ion `(CrO_(4)^(2-))`, the ionisation of `Ag_(2)CrO_(4)` is supressed and solubility of `Ag_(2)CrO_(4)` decreases i.e., `[Ag^(o+)]` decreases.
