When electricity is passed through a solution of `AlCl_(3)` and `13.5g` of `Al` is deposited, the number of Faraday of electricity passed must be ………………….F
a.0.5
b.1.0
c.1.5
d.2.0

A

2

B

1.5

C

1

D

0.5

Text Solution

Verified by Experts

The correct Answer is:
B
`Al^(3+)+underset(3F)(3e^(-)rarrunderset(1"mole"=27g)(Al)`
To produce 27g of Al electricity required=3F.
Thus to produce 3.5g of Al electricity required.
`(3)/(2)=1.5F`
