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
= 800 AAccording 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
