1.	When an aqueous solution of `AgNO_3` is electroysed between platinum electrodes, the substances liberted at anode and cathode areA. silver is deposited at cathode and `O_2` is liberated at anodeB. silver is deposited at cathode and `H_2` is liberated at anodeC. hydrogen is liberted at cathode and `O_2` is liberated at anode.D. silver is deposited at cathode and Pt is dissolved in electrolyte.
Answer» Correct Answer - A `{:("At cathode",Ag_((aq))^(+)+e^(-) to Ag_((s))),("At anode:",2OH_((aq))^(-) to 1/2O_(2(g))+H_2O_((l))+2e^(-)):}`
