How much copper is deposited on the cathode if a current of 5 A is passed throgh a solution of `CuSO_4` for 45 minutes ?

What happens when NH_3 is passed through CuSO_4 solution ?

Define electrochemical equivalent and chemical equivalent. How are they related with each other ? A current of 5 amperes is passed through an electrolyte for 15 minutes when 3 gms of the metal was deposited. Calculate the electrochemical equivalent of the metal.

How many moles of copper will be deposited at the cathode by passing 1.5 faraday of electricity through a sol^n of CuSO_4 ? (At. Mass of Cu =63.5).

Find the mole ratio of 'Cu' and 'Ag' deposited when same quantity of charge is passed through solutions of CuSO_4 and AgNO_3 separetely (Ag = 108, Cu - 63.5)

What happens when: H_2S gas is passed through CuSO_4 solution.
