Question

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)

Options

A.1.76 × 10-3 kg
B.9.67 × 10-3 kg
C.17.61 × 10-3 kg
D.3.67 × 10-3 kg

Solution

Current, I = = 800 A
According to the Faraday′s first law electrolysis Mass of clorine liberated, m = zIt.
m = (0.367 × 10-6 kg/C)(800A) (60 s)
m = (60s)
= 17.61 × 10-3 kg
