Two half cells in a galvanic cell consist of one iron Fe solid electrode in a solution of iron II sulphate FeSO4 aq as well as a silver Ag solid electrode in a silver nitrate AgNO3 aq solution.
a) Presume the cell is operating as a galvanic cell state the overall as well as half-cell reactions. Explain what will happen to the mass of the cathode while the cell is operating.
b) Repeat parts a), presuming that the cell is operating as an electrolytic cell.
