The spontaneous reaction that takes place in this cell is

Options

  1. AZn + Ni Zn ²⁺+ Ni ²⁺
  2. BZn + Ni ²⁺ Zn ²⁺+ Ni
  3. CNi + Zn ²⁺ Ni ²⁺+ Zn
  4. DNi ²⁺+2 ~K 2 ~K ⁺+ Ni

Correct answer

B. Zn + Ni ²⁺ Zn ²⁺+ Ni

Step-by-step solution

Zn is at lower potential, it will be oxidised and the cell reaction will be Zn (s)+ Ni ²⁺(a q) Zn ²⁺(a q)+ Ni (s)
