Predict the products of electrolysis of the following :

(i) An aqueous solution of AgNO₃ with silver electrodes 

(ii) An aqueous solution of AgNO₃ with platinun electrodes 

(iii) A dilute acqueous solution of H₂SO₄ with platinum electrodes 

(iv) An aqueous solution of CuCI₂ with platinum electrodes.

(Given E°_Ag+/Ag = +0.80  V,  E°_Cu2+/Cu = +0.34 V)
