In the cell reaction Ni(s) + 2Ag+(aq) → Ni2+(aq) + 2Ag(s), what is the role of Ni(s)?

Options

  1. ANi(s) is the anode.
  2. BNi(s) is the cathode.
  3. CNi(s) is a spectator ion.
  4. DNi(s) is a catalyst.

Correct answer

B. Ni(s) is the cathode.

Step-by-step solution

In the cell reaction Ni(s) + 2Ag+(aq) → Ni2+(aq) + 2Ag(s), Ni(s) is the cathode where reduction occurs.
