Current Electricity

  1. In producing chlorine through electrolysis, 100 watt 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/ coulomb.​​
    1. 21.3 mg ​
    2. 24.3 mg
    3. 13.6 mg ​
    4. 17.6 mg
Correct Option: D

Power = V × I

I =
Power
=
100
V125

E.C.E. of chlorine is 0.367 × 10–6 kg/coulomb
Charge passing in one minute =
100
× 60 = 48 coulomb
125

Chlorine precipitated = 0.367 × 10–6 × 48
17.6 × 10–6 kg
= 17.6 mg
