1.	An aqueous solution `FeSO_(4).Al_(2)(SO_(4))_(3)` and chrome alum is heated with excess of `Na_(2)O_(2)` and fltered. The materials obtained areA. 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 - C The filtrate is yellow due to `CrO_(4)^(2-)` ion and residue is brown due to `Fe(OH)_(3)`
