  • a)
    +2.03 V
  • b)
    -2.03 V
  • c)
    +2.71 V
  • d)
    -2.71 V
Correct answer is option 'C'. Can you explain this answer?

The cell reaction of the cell is Mg(s) + Cu+2 (aq)→ Cu(s) + Mg+2 ...
Given Data
- Standard reduction potential of magnesium (Mg): -2.37 V
- Standard reduction potential of copper (Cu): +0.34 V

Calculation
1. The standard cell potential (EMF) can be calculated using the formula:
Ecell = Ecathode - Eanode
Ecell = E(Cu) - E(Mg)
Ecell = (+0.34 V) - (-2.37 V)
Ecell = +0.34 V + 2.37 V
Ecell = +2.71 V

Answer
Therefore, the standard EMF of the cell is +2.71 V. Hence, option 'C' is the correct answer.
