During the electrolytic production of aluminium , the carbon anodes are replaced from time to time because

A

carbon convents `Al_(2)O_(3)" to "Al`

B

oxygen librated at the carbon anode reacts with anodes to form `CO_(2)`

C

the carbon perevents atmosphere oxygen from coming in corbon with aluminum

D

the xcarbon anode get decayed

Text Solution

Verified by Experts

The correct Answer is:
b
The oxigen librated attached the carbon anodes
`2C(s) + O_(2) (g) rarr 2CO(g)`
`C(s) + O_(2)(g) rarr CO_(2) (g)`
Thus, anode are replace frequentity
