A quantity of electrical charge that brigns about the depositiion of `4.5g Al` from `Al^(3+)` at the cathode will also produce the following volume `(STP)` of `H_(2)(g)` from `H^(o+)` at the cathode.

A

` 11. 2 L`

B

` 44.8 L`

C

` 5.6 L`

D

` 22 .4 L`

Text Solution

Verified by Experts

The correct Answer is:
C
Eq. of `H_2 =` Eq . Of `Al = ( 4.5)/(27 .3) =0.5`
`:. 1 eq .H_2 = 11 . 2 L`
` :. 0 5 eq . H_2 = 5. 6 L` .
