An aqueous solution of 'FeSO4.Al2(SO4)3'...

An aqueous solution of 'FeSO4.Al2(SO4)3' and chrome alum is heated with excess of Na2O2 and filtered. The materials obtained are

A

A colourless filtrate and a green residue

B

A yellow filtrate and a green residuc

C

A yellow filtrate and a brown residue

D

A green filtrate and a brown residue

Text Solution

Verified by Experts

The correct Answer is:
C
In the presence of peroxide, chromium ions are oxidised to chromate ions which give an yellow filtrate. Ferric ions form brown precipitate of `Fe(OH)_3.`,
