Q. In producing chlorine by electrolysis 100 kW power at 125 V is being consumed. How much chlorine per minute is liberated? (E.C.E. of chlorine is 0.367 × 10⁻⁶ kg/C)
A) 3.67 × 10⁻³ kg
B) 1.76 × 10⁻³ kg
C) 9.67 × 10⁻³ kg
D) 17.61 × 10⁻³ kg
Explanation
[Solution from source] I = P/V = 100000/125 = 800 A. In one minute m = ZIt = 0.367 × 10⁻⁶ × 800 × 60 = 17.6 × 10⁻³ kg. 3.67 × 10⁻³ kg would need a far smaller charge. Answer (4).
