Question

The electrolytic manufacture of chlorine gas from a sodium chloride solution is carried
out by the following reaction:
2 NaCl + 2 H2O → 2 NaOH + H2 + Cl2
How many kilograms of Cle can be produced from 10 m3 of brine solution containing 5% by
weight of NaCl? The specific gravity of the solution relative to that of water at 4°C is 1.07.​

Answer 1

Answer:

0.01 moles of H

2

will require 2×0.01=0.02 moles of electrons or 0.02 faradays.

96500

I(A)×t(s)

=0.02

96500

1000mA/A

10mA

×t(s)

=0.02

t=19.3×10

4

s

Hence, the corret option is B
