In electrometallury of aluminium , what will happen if graphite rodes are not used as anode and are replaced by some other metal ?A. `O_(2)` liberated at node will react with aluminium to give back `Al_(2)O_(3)`B. `F_(2)` will be liberated at anode instead of `O_(2)`C. The process of electrometallurgy will become non-spontaneousD. Aluminium oxide splits into `Al^(3+)` and `O^(2-)` ions only in presence of graphite

1.	In electrometallury of aluminium , what will happen if graphite rodes are not used as anode and are replaced by some other metal ?A. `O_(2)` liberated at node will react with aluminium to give back `Al_(2)O_(3)`B. `F_(2)` will be liberated at anode instead of `O_(2)`C. The process of electrometallurgy will become non-spontaneousD. Aluminium oxide splits into `Al^(3+)` and `O^(2-)` ions only in presence of graphite
Answer» Correct Answer - A If some other metal is used as the anode other than graphite then the oxygen liberated at anode will convert some Al to `Al_(2)O_(3)`.
