An aqueous solution of `FeSO_4.Al_2(SO_4)_3` and chrome alum is heated with excess of `Na_2O_2` and filtered. The materials obtained are

A

A colourless fitrate and a green residue

B

A yellow fitrate and a green residue

C

A yellow fitrate and a brown residue

D

A green fitrate and a green brown

Text Solution

Verified by Experts

The correct Answer is:
c
In the presence of peroxide, chromium ions are oxidised to chromate ions which give a yellow fitrate ferrie ions form brown precipitate of `Fe(OH)_(3)`
