MCQ Solution: Electrochemistry
In producing chlorine through electrolysis 100 watt power at 125 V is being consumed. How much chlorine per minute is liberated ? Electrochemical Equivalent of chlorine is 0.367 × 10−6 kg/coulomb:
1) 21.3 mg
2) 17.6 mg
3) 24.3 mg
4) 13.6 mg
SOLUTION
Power consumed in electrolysis =100 W
Current in flow in this solution, i=100 / 125=0.8 A
According to first law of Faraday's law
M=ZQ and Q=it
So,
M=Zit
Z=0.367×10−6; i=0.8 A;t=60 s = =17.6 mg
