For the reduction of NO_(3)^(c-) ion in an aqueous solution, E^(c-) is +0.96V , the values of E^(c-) for some metal ions are given below : i.V^(2+)(aq)+2e^(-)rarr V, " "E^(c-)=-1.19V ii. Fe^(3+)(aq)+3e^(-) rarr Fe, " "E^(c-)=-0.04V iii. Au^(3+)(aq)+3e^(-) rarr Au, " "E^(c-)=+140V iv. Hg^(2+)(aq)+2e^(-) rarr Hg, " "E^(c-)=+0.86V The pair (s) of metals that is // are oxidized by NO_(3)^(c-) in aqueous solution is // are

Statement-I: In the Daniel cell, if concentration of Cu^(2+) and Zn^(2+) ions are doubled the emf of the cell will not change. Because Statement-II: If the concentration of ions in contact with the metals is doubled, the electrode potential is doubled.
