The Voltage of an Electrochemical Cell
The Voltage of an Electrochemical Cell (Half Cell Analysis)The Voltage is a measure of the difference in electrical potential between combinations of chemicals produce different half reactions have been given an electrical potential ( Voltage ) based on the standard hydrogen half cell which was assigned a Voltage of zero. Those substances with a positive Voltage (Eo) gain electrons more easily than substances with a negative Voltage are not as easily reduced as the Zn /Zn2+//Cu2+/Cu (Daniell Cell)Rx n at the anode Zn(s) Zn2+ + 2e- + v Rx n at the cathode Cu2+ + 2e- Cu(s) + v Zn(s) + Cu2+ Zn2+ + Cu(s) + vA positive Voltage indicates the reaction is spontaneous in the direction each of the following Electrochemical combinations:- complete each half reaction- complete the net reactio
