In an aqueous solution containing Cu^(2+), Ag^(+), Sn^(2+) and Hg_(2)^(2+) ions, the concentration of each ion is 1 (M). Electrolysis of the solution is carried out in presence of inert electrodes. Given: E_(Hg_(2)^(2+)|Hg)^(@)=+0.79V and E_(Sn^(2+)|Sn)^(@)=-0.14V. If the voltage applied on the electrodes is gradually increased, then the metal that will deposit first and that at the end of the process at the cathode, respectively, are -

1.	In an aqueous solution containing Cu^(2+), Ag^(+), Sn^(2+) and Hg_(2)^(2+) ions, the concentration of each ion is 1 (M). Electrolysis of the solution is carried out in presence of inert electrodes. Given: E_(Hg_(2)^(2+)\|Hg)^(@)=+0.79V and E_(Sn^(2+)\|Sn)^(@)=-0.14V. If the voltage applied on the electrodes is gradually increased, then the metal that will deposit first and that at the end of the process at the cathode, respectively, are -
