Question

To deposit one litre of hydrogen at 22.4 atmosphere from acidulaled water, the quantity of electricity that must pass through is

• A. 1 coulomb
• B. 22.4 coulomb
• C. 96500 coulomb
• D. 193000 coulomb

Answer 1

Answer: (D)

193000 coulomb

Answer 2

$V_{2} = \frac{22.4 \times 1}{1} = 22.4litre$ at NTP

11.2 litre of H₂ is liberated by 96,500 C

∴ 22.4 litre of H₂ is liberated by 96500 × 2 = 1,93,000 C
