Question

The quantity of current(amp) required to liberate
H2 gas at S.T.P at the rate of 1C.C per second
1) 2.61
2) 8.61 3) 4.61
4) 0.61​

Answer 1

Answer:

2H+ + 2e− → H2

2 F is required to liberate 22.4 L of  H2 gas;

1000cc = 1L

112 cc = 0.112 L

for 22.4 L we require 193000 C of charge, ( 1F = 96500 C )

so, 0.112 L we require charge = 22.4193000∗0.112

Hence, the quantity of charge required = 965C
