• question_answer 37) Predict the products of electrolysis in each of the following: (i) An aqueous solution of$AgN{{O}_{3}}$ with silver electrodes. (ii) An aqueous solution of $\text{AgN}{{\text{O}}_{\text{3}}}$with platinum electrodes. (iii) A dilute solution of sulphuric acid using platinum electrodes. (iv) An aqueous solution of $CuC{{l}_{2}}$ with platinum electrodes.

(i) Anode $Ag\to A{{g}^{+}}+{{e}^{-}}$ Cathode $A{{g}^{+}}+{{e}^{-}}\to Ag$ (ii) Cathode $A{{g}^{+}}+{{e}^{-}}\to Ag$ Anode $2O{{H}^{-}}\to {{H}_{2}}O+\frac{1}{2}{{O}_{2}}+2{{e}^{-}}$ (iii) In dilute${{H}_{2}}S{{O}_{4}}$, electrolysis of water takes place. ${{H}_{2}}O\rightleftharpoons {{H}^{+}}+O{{H}^{-}}$ Cathode $2{{H}^{+}}+2{{e}^{-}}\to {{H}_{2}}\uparrow$ Anode $2O{{H}^{+}}\to {{H}_{2}}O+\frac{1}{2}{{O}_{2}}+2{{e}^{-}}$ (iv) $CuC{{l}_{2}}\to C{{u}^{2+}}+2{{e}^{-}}\to Cu$ Cathode $C{{u}^{2+}}+2{{e}^{-}}\to Cu$ Anode $2C{{l}^{-}}\to C{{l}^{2}}+2{{e}^{-}}$
