Question

How many coulombs of electricity are required for
the oxidation of 1 mol of H,O to 0, ?
(1) 9.65 x 104 C (2) 4.825 105 C
(3) 1.93 x 105 C (4) 1.93 x 104 C​

Answer 1

Answer:

1)9.65*10^4 C

2OH^- --- 2e = H2O + 1/2 O2

or,, 2H^+ + 2e = H2

2 mole electron charge =2 mole of H/OH

we know,1 mole of electron charge =96500C

For 1 mole of H/O to O= 2*96500/2 Coulombs =9.65*10^4 C
