  • a)
    Mn > Ni > M
  • b)
    Ni > Mn > M
  • c)
    Mn > M > Ni
  • d)
    M > Ni > Mn
Correct answer is option 'C'. Can you explain this answer?

An unknown metal M displaces nickel from nickel (II) sulphate solution...
Explanation:

Displacement reactions:
- When metal displaces another metal from its salt solution, it indicates the relative reducing power of the metals.
- In this case, the unknown metal M displaces nickel from nickel (II) sulphate solution but does not displace manganese from manganese sulphate solution.

Order of reducing power:
- The correct order of reducing power can be determined based on the displacement reactions observed.
- Since M displaces Ni but not Mn, it means M is more reactive than Ni but less reactive than Mn.
- Therefore, the correct order of reducing power is Mn > M > Ni.

Correct answer:
- The correct order of reducing power is Mn > M > Ni, which is represented by option 'C'.
