To determine

Consider a magnesium $\left(\text{Mg}\right)$-iron $\left(\text{Fe}\right)$ galvanic cell that consists of $\text{Mg}$ electrode in a $1M$ ${\text{MgSO}}_4$ electrolyte solution and $\text{Fe}$ electrode in a $1M$ ${\text{FeSO}}_4$ electrolyte solution. Both electrolytes are separated by a permeable wall and entire cell is maintained at

$25°\text{C}$. Find the following:

1. (a) Which electrode is the anode?
2. (b) Which electrode corrodes?
3. (c) The direction of flow of electrons.
4. (d) The direction of the movement of anions in the solution.
5. (e) The direction of the movement of cations in the solution.
6. (f) The anodic half-cell reaction equation.
7. (g) The cathodic half-cell reaction equation.
