Question

Q. Calculate the following Electrode Potential at 25°C ?

1) Cu++(0.1 M)/Cu.
2)Cu++(0.01 M)/Cu.
3)Cu++(0.001 M)/Cu
E°Cu++/Cu = 0.34 V (Given)

Plz solve it guy's..​

Answer 1

Answer:

1)0.3045volt

2)0.2809volt

3)0.25135volt

Explanation:

here n=2

given cu++/cu=0.34v

therefore,

1) E=0.34+0.0591/2*log[0.1]

=0.34+0.02955*(-1)

=0.34-0.02955

=0.3045volt

2)E=0.34+0.0591/2*log[0.01]

=0.34+0.02955(-2)

=0.34-0.0591

=0.2809volt

3)E=0.34+0.0591/2*log[0.001]

=0.34+0.02955(-3)

=0.34-0.08865

=0.25135volt

plz mark it brainliest please
