Well you need to comment on how the anode would need to be inert, like graphite, platinum or titanium. Otherwise the cell will act like a galvanic cell, and the anode will react in the cell. Then put in equations and comment on the reduction potentials of the different substances - Chlorine, Water. For example if the anode was made of copper, it has a possibility to react. And if you have a neap test, shouldn't it come with suggested answers. Anyway good luck
