Question 1 Report

What quantity of electricity will liberate 0.125 mole of oxygen molecules during the electrolysis of dilute sodium chloride solution?
Answer Details

4OH ⇒ 2H 2 O + O 2  + 4e-

From the equation:

1 mole of Oxygen requires 4e 

i.e 1 mole of Oxygen requires 4F,

where 1F = 96,500 C

[ 4 X 96,500 X 0.125 ] ÷ 1

= 48,250 C
