Answer 2

For the given reaction, Ni(s) + 2Ag+ (aq) → Ni2+ (aq) + 2Ag(s), the individual half cell reactions will be-

• Ni → Ni²⁺ + 2e⁻   (Oxidation half reaction)
• Ag⁺ + e⁻ → Ag    (Reduction half reaction)

The standard electrode potential of Ni/Ni²⁺ is 0.236Vwhile that of Ag⁺/Ag is 0.8V.

So, when nickel and silver electrodes are taken, silver will act as the as  cathode and nickel will be the anode.
