Question

the total volume of dry gaseous product at stp when 3 moles of electron are transferd from anode to cathode in the electrolisis of water is​

Answer 1

Answer:

According to first law of faraday,

Ewt

Wt

=

F

Q

F

Q

= farady No.

∴ charge of 1 mol of electrons is equal to 1 farady.

Ewt

Wt

=

F

ne

∴Q=ne and n=4

mole×V.f.=

F

4F

mole×2=4

mols of H

2

O=2

Hence the two moles of H

2

O will decomposed into it's gaseous components

2H

2

O⟶2H

2

+O

2

2moles of H

2

(at cathode) and 1mol of O

2

(at anode) will produce.

moles=

22.4

v

So volume of H

2

and O

2

will be = 44.8+22.4 = 67.2
