An electrochemical cell consists of a silver electrode in contact with 346 mL of 0.1 M AgNO3 solution and a magnesium electrode in contact with 288 ml of a 0.1 M Mg(NO3)2 solution (a) calculate the value for E for the cell at 25oC (b) A current is drawn from the cell until 1.20 g of silver have been deposited at the silver electrode. Calculate the value of E for the cell at that stage of operation.
