An experimenter wishes to test the hypothesis that a concentration difference alone can produce a voltage in an electrochemical cell. In order to test her hypotheses, she constructs the cell shown below, where both sides of the cell contain AgNO3, with concentrations shown in the diagram. She will use the voltmeter shown to determine what voltage, if any, exits across the electrodes at different times after the circuit is closed.
The table that follows shows the voltage in the cell as a function of the time that current has been allowed to flow in the circuit. It also displays the concentration of silver ion on each side of the cell.
