In the electrolysis of acidulated water, it is desired to obtain 1.12 cc of hydrogen per second under STP condition. The current to be passed is
Options
- A1.93 ~A
- B9.65 ~A
- C19.3 ~A
- D0.965 ~A
Correct answer
B. 9.65 ~A
Step-by-step solution
No. of moles of H ₂= 1.12 22400 No. of equivalence of hydrogen = 1.12 2 22400 =10⁻⁴ No. of Faradays required =10⁻⁴ Current to be passed in one second aligned &=96500 10⁻⁴ &=9.65 ~A aligned
