Question

What would happen when a solution of potassium chromate is treated with an excess of dilute nitric acid?
(a) $Cr_2O_7^{2-}$ and H₂O are formed
(b) $CrO_4^{2-}$ is reduced to +3 state of Cr
(c) $CrO_4^{2-}$ is oxidized to +7 state of Cr
(d) Cr³⁺ and $Cr_2O_7^{2-}$ are formed

Answer 1

(A) because nitric acid being a strong oxidising agent oxidises H2 into water thus forming cr2 o7 and water.
