Question

How much charge is required for the reduction of 1 mole of zn by positive to zn?

Answer 1

answer : 193000C

explanation : we have to find the amount of charge is required for the reduction of 1mole of Zn²+ to Zn.

see half reduction reaction...

Zn²+ + 2e- ⇔ Zn

here it is clear that, for one mole of reduction of Zn, 2moles of electron is required.

we know, 1 mole of electron is equivalent to 96500C charge.

so, 2 mole of electron ⇒2 × 96500C = 193000 C

hence, 193000C charge is required for the reduction of one mole of Zn²+ to Zn.
