The electric charge on the electron is 1...

The electric charge on the electron is `1.602xx10^(-19)` coulomb. How much charge is present on 0.1 mole of `Cu^(2+)` ions?

Text Solution

Verified by Experts

Charge on one mole of electrons.
`=6.02xx10^(23)xx1.602xx10^(-19)` coulomb
=96500 coulomb =1 faraday.
Charge on one mole of `Cu^(2+)` ions
`=2xx96500` coulomb=2 faraday
Charge on 0.1 mole of `Cu^(2+)` ions
`=0.1xx2=0.2` faraday.
