This question is about the Ag+(aq)|Ag(s) half-cell.
A student was asked to plan an experiment to measure the standard electrode potential of the Ag+ (aq)|Ag(s) half-cell.
(1)
Identify three mistakes in this diagram and the modifications that should be made to correct them.

The standard electrode potential, , of the Ag+ (aq) | Ag (s) half-cell is +0.80 V.
The effect of changing the concentration of the ions on the value of the electrode potential, E, in this half-cell is calculated using the equation.
where T is the temperature in kelvin and R is the gas constant.
The electrode potential of a Ag+ (aq) | Ag (s) half-cell was measured at 20 °C and found to be +0.72 V.
Calculate the concentration of silver ions, in mol dm-3, in this half-cell.
