Question

In producing chlorine through electrolysis $100\, W$ power at $125\, V$ is being consumed. How much chlorine per minute is leberated? ($ECE$ of chlorine is $0.367 ? 10^{-6}\, kg/C$)

• A. $24.3\,mg$
• B. $16.6\,mg$
• C. $17.6\,mg$
• D. $21.3\,mg$

Answer 1

Answer: (D)

$21.3\,mg$

Answer 2

$P=100\,W$ and $V=125\,V$
$P=VI \Rightarrow I=\frac{P}{V}=\frac{100}{125}A$
Mass of chlorine liberated = zit
$=0.367\times10^{-6}\times\frac{100}{125}\times60$
$=17.6\,mg$
