The sam quantity of electricity is passed through `H_2 SO_4` and `HCI` solutins of same concentration. The amount of hudrogen liberated from `H_2SO_4` as cmpared to that from `HCI` is.

Options

A. the same
B. twice as such
C. one half as such
D. dependent on concentration.

Answer

B

Explanation

For `H_(2)S_(2) hArr2H^(+)+SO_(4)^(2-)`
`2xx96500 C` liberates `1` mole of `H_2`
For ` HCI rarr H^(+) + CI^(-)`
`96500 C` liberates `/12` mole of `H_2` and therefore `2xx96500 C`.
