Find the number of electrons involved in the electro-deposition of 63.5 g of copper from a solution of copper sulphate is:

Aqueous solution of copper sulphate

If 96500 coulombs of electricity liberates one gram equivalent of any substance, the time taken for a current of 0.15 amperes to deposite 20 mg of copper from a solution of copper sulphate is (Chemical equivalent of copper = 32)

How long will it taje 5 ampere of current to deposit 2 g of copper from a solution of copper sulphate ? (Given : CE of copper =32, F=96500 coulomb)

Reddish brown deposit formed on iron nails kept in a solution of copper sulphate is :

Reddish brow deposit formed on iron nails kept in a solution of copper sulphate is :

Copper can be displaced from aqueous solution of copper sulphate by adding

One Faraday of electricity when passed through a solution of copper sulphate deposits .

Iron is _______ copper in the electrochemical series and hence displaces _____ from a solution of copper sulphate.

Which metal can deposit copper from copper sulphate solution ?
