The quantity of charge required to obtain one mole of aluminium from `Al_(2)0_(3)` is

A

1F

B

6F

C

3F

D

2F

Text Solution

Verified by Experts

The quantity of charge required to obtain one mole of aluminium from `Al_(2)O_(3)` is equal to number of electron required to convert `Al_(2)O_(3)` to Al.
`Al^(3+)(aq)overset(+3e)rarrAl(s)`
Hence, total 3F is required
