MCQ
Acidified solution of chromic acid on treatment with hydrogen peroxide yields
- A$Cr{O_3} + {H_2}O + {O_2}$
- B$C{r_2}{O_3} + {H_2}O + {O_2}$
- ✓$Cr{O_5} + {H_2}O$
- D${H_2}C{r_2}{O_7} + {H_2}O + {O_2}$
✓
Answer
Correct option: C.
$Cr{O_5} + {H_2}O$
c
(c) ${K_2}C{r_2}{O_7} + {H_2}S{O_4} + 4{H_2}{O_2} \to {K_2}S{O_4} + 2Cr{O_5} + 5{H_2}O$
(c) ${K_2}C{r_2}{O_7} + {H_2}S{O_4} + 4{H_2}{O_2} \to {K_2}S{O_4} + 2Cr{O_5} + 5{H_2}O$
