Question

In producing chlorine by electrolysis 100 kW power at 125 V is being consumed. How much chlorine per minute is liberated?
(ECE of chlorine is 0.367×10*-6 kg/C) [AIPMT (Prelims)-2010]
​

Answer 1

I've done according to 0.367×10^-6 KgC^-1

Answer 2

Answer:

The chlorine per minute liberated is $17.616\times10^{-3}\ kg$.

Explanation:

Given that,

Power = 100 kW

Voltage = 125 V

We nee to calculate the current

Using formula of power

$P = V\times I$

$I=\dfrac{P}{V}$

Where, P = power

V = voltage

Put the value into the formula

$I=\dfrac{100\times10^{3}}{125}$

$I= 800\ kg/m$

The chlorine liberated =$ECE\times I$

The chlorine liberated =$0.367\times10^{-6}\times800$

The chlorine liberated =$0.0002936\ kg/s= 0.0002936\times60\ kg/m$

The chlorine liberated = $0.017616\ kg/m=17.616\times10^{-3}\ kg/m$

Hence, The chlorine per minute liberated is $17.616\times10^{-3}\ kg$.
