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) :
Answer & explanation
Correct answer: option 4
Power = 100kW
Voltage = 125V
Power = Vi
100 × 103 = 125i
i = \(\frac{100000}{125}\)
i = 800A
We know from 1st law of electrolysis
m = Zit (Z= E.C.E.)
= \(\frac{0.367}{1000}\) × 10-6 × 800 × 60
= 367 × 48 × 106kg
= 1.76 × 10-2kg
