It is possible to keep `CuSO_4` solution in an iron dish?

H_(2) gas is passed through CuSO_(4) solution

Which one is correct for electrolysis of CuSO_4 solution using Cu electrode.

Reaction at the anode during the electrolysis of aqueous CuSO_(4) solution in presence of Cu electrode is -

If electrolysis of aqueous CuSO_(4) solution is carried out using Cu-electrodes, the reaction taking place at the anode is:

If the quantity of electricity required to liberate 2.6267 g of gold from a solution of gold salt is used for the the electrolysis of CuSO_(4) solution in presence of copper anode, then 1.26 g of copper gets dissolved. Find the oxidation number of gold in the gold salt. [Cu=63, Au=197]

Iron can displace Cu from CuSO_(4) solution, but Ag can not. Explain.

A metal X on heating in nitrogen gas gives Y, Y on treatment with H_2 O gives a colourless gas which then passed through Cuso_4 solution gives a blue colour. Y is

During the electrolysis of CuSO_(4) solution in presence of cooper electrodes, the Cu - anode is depleted. Why ?

Can CuSO_(4) solution be stored in a zinc container?

FeSO_4 solution mixed with (NH_4)_2SO_4 solution in 1:1 molar ratio gives the test of Fe2+ ion but CuSO_4 solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of Cu2+ ion. Explain why?.
