Question

106.
If 0.50 L of a 0.60 M SESO, solution is electrolyzed for a
period of 30 min using a current of 4.60 A. If inert
electrodes are used then what is the final concentration of
Sn2+ remaining in the solution ?[atomic wt. of Sn=119]
1.0.342 M
2.0.6 M
3.0.389 M
1
4.0.514 M​

Answer 1

Explanation:

Given : 0.6 mol in 1 L

then in 0.5 L = 0.3 mol of Sn

2+

Mass deposited W = zit

=

2×96500

119

×4.6×1800

= 5.1 g

Rest mass in solution = 30.6 gm

Now molority of solution =

119×1

30.6

= o.257 M
