The molarity of the Cu+ and Zn+ solutions used in the setup of the electrochemical cell was 1 M. Explain why the voltage was not equal to the standard cell potential for the Cu/Zn redox reaction at all times during the experiment. Experiment 2: Concentration and Voltage: Initial Cell Potential After Adding 6 mL of KHAsO4 After Adding Another 6 mL of KHASO4 After Adding Another 6 mL of KHASO4 Voltage (V) initial: 1.100 after adding 6ml #1: 1.090 after adding 6ml #2: 1.077 after adding 6ml #3: 0.000
