Q. What would happen when a solution of potassium chromate is treated with an excess of dilute nitric acid?
A) ${Cr}^{3 +}\ and\ {Cr_{2}O}_{7}^{2 -}are\ formed$
B) ${Cr_{2}O}_{7}^{2 -}and\ H_{2}O\ are\ formed$
C) ${CrO}_{4}^{2 -}\ is\ reduced\ to + 3\ state\ of\ Cr$
D) None of the above
Explanation
(b)
${CrO}_{4}^{2 -} + 2H^{+}\ \longrightarrow {Cr}_{2}O_{7}^{2 -} + H_{2}O$
