What would happen when a solution of potassium chromate is treated with an excess of dilute nitric acid?

Accepted Answer

When a solution of potassium chromate is treated with an excess of dilute nitric acid. Potassium dichromate and

H_{2} O

are formed.

2 K_{2} C r O_{4} + 2 H N O_{3} \to K_{2} C r_{2} O_{7} + 2 K N O_{3} + H_{2} O

Hence

C r_{2} {O_{7}}^{-}

and

H_{2} O

are formed.
