Q. Acidified solution of chromic acid on treatment with hydrogen peroxide yields
A) $CrO_{5} + H_{2}O$
B) $H_{2}Cr_{2}O_{7} + H_{2}O + O_{2}$
C) $Cr_{2}O_{3} + H_{2}O + O_{2}$
D) $CrO_{3} + H_{2}O + O_{2}$
Explanation
(a)
$K_{2}{Cr}_{2}O_{7} + H_{2}{SO}_{4} + 4H_{2}O_{2} \rightarrow K_{2}{SO}_{4} + 2CrO_{5} + 5H_{2}O$
