An acidic solution of copper (II) sulphate containing some contaiminations of zinc and iron (II) ions was electrolysed till all the copper is deposited. If electrolysis is further continued for sometime, the product liberated at cathode is

An acidic solution of copper (II) sulphate can be stored in iron vessel.

An acidic solution of Cu^(2+) salt containing 0.4 g of Cu^(2+) is electrolysed until all the copper is deposited. The electrolysis is continued for seven more minutes with the volume of solution kept at 100 ml and the current at 1.2 amp. Calculate the volume of gases evolved at NTP during the entire electrolysis.

An acidic solution of Cu^(2+) ions containing 0.4 g of Cu^(2+) ions is electrolysed until all the copper is deposited. Calculate the volume of oxygen evolved at N.T.P.

An acidic solution of Cu^(2+) ions containing 0.4 g of Cu^(2+) ions is electrolysed until all the copper is deposited. Calculate the valume of oxygen evolved at N.T.P.
