Consider an acidic chromate-dichromate system at equilibrium in which the color is an orange-yellow. The reaction is represented
goldenfox [79]

Answer:

The equilibrium will move in forward direction.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

Cr_2O_7^{2-}(aq)+H_2O(l)\rightleftharpoons 2CrO_4^{+}(aq)+2H^+(aq)

On addition of base at the equilibrium, the hydroxide ions of the base will neutralize the hydrogen ions and lowering in concentration of hydrogen ion will be observed.

So, on lowering of concentration of hydrogen ions the equilibrium will move in direction in accordance to Le Chatelier’s Principle .The equilibrium will move in forward direction.
