Q. How many coulombs of electric charge must pass through acidulated water in order to release 22.4 L Of hydrogen at NTP?
A) 96500 Faraday
B) 193000 coulomb
C) 196500 Faraday
D) 96500 coulomb
Explanation
(b) 11.2 L of $H_{2}$ is liberated by 96500 C 22.4 L of $H_{2}$ is liberated by
96500$\times 2 = 193000$ C.
