Question

Question No. 26
• Two electrolytic cells, one
containing cuprous chloride and
other cupric chloride are connected in
series. The ratio of ions deposited at
cathode in two cells when electricity is
passed through the cells will be ...​

Answer 1

Answer:

answer is 3:2

Step-by-step explanation:

In FeCl

2

, Fe

+2

is present

& in FeCl

3

, Fe

+3

is present

At cathode:−Fe

+2

+2e

−

⟶Fe−(i)

Fe

+3

+3e

−

⟶Fe−(ii)

Equivalent weight of Fe in (i)=

n

Atomicweight

=

2

Atomicweight

Equivalent weight of Fe in (ii)=

3

Atomicweight

∴ Ratio of iron deposited at cathodes=

A/3

A/2

=3:2
