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) : 

17.61 × 10^–3 kg

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
