Expert Answer:

Given:

We have 1 mol of H2O

1 mol of H2O will give one atom of O

begin mathsize 11px style straight H subscript 2 straight O space rightwards arrow space straight H subscript 2 space space plus space space space 1 half straight O subscript 2 Charge space on space straight O space equals space – space 2 straight O subscript 2 minus space rightwards arrow space 1 half straight O subscript 2 space space plus space space 2 straight e to the power of minus end style

Electricity required for the oxidation of 1 mole of H2O to O2 = n F

(Here, n= 2)

= 2 × 96487 Coulombs

= 192974 Coulombs

= 1.93 × 105 Coulombs
