Question

The quantity of charge required to obtain one mole of aluminium from `Al_(2)0_(3)` is
A. 1 F
B. 6 F
C. 3 F
D. 2 F

Answer 1

Correct Answer - C
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_(2)O_(3)` to `Al Al^(3+)(aq) overset(+3e)rarrAl(s)` Hence, total 3F is required.
