The equilibrium Cr2O^2- 7 ⇌ 2CrO^2- 4 is shifted to the right in

Question

The equilibrium \(Cr_2 O ^{2-}_7 \rightleftharpoons 2 Cr O^{2-}_4\) is shifted to the right in :

(1) an acidic medium 

(2) a basic medium 

(3) a weakly acidic medium 

(4) a neutral medium

Answer 1

Correct option is (2) a basic medium 

\(Cr_2 O ^{2-}_7 \underset {H^+}{\overset{OH^-} {\rightleftharpoons }} 2CrO^{2-}_4\)
