An aqueous solution of `FeSO_(4),Al_(2)(SO_(4))_(3)` and chrome alum i

1.	An aqueous solution of `FeSO_(4),Al_(2)(SO_(4))_(3)` and chrome alum is heated with excess of `Na_(2)O_(2)` and filtered. The materials obtained asA. A colourless filtrate and a green residueB. A yellow filtrate and a green residueC. A yellow filtrate and a brown residueD. A green filtrate and a brown residue
Answer» Correct Answer - B Yellow filtrate is due to chromate ions `(CrO_(4)^(- -))` and green residue to due to `Fe(OH)_(2)`.
