C. Copper - Nickel N NI(NO,). (1.O M) || Cu Cucl, (1.0 M) 1. Draw the schematic of the electrochemical cell that you created including all the components (metals, solutions, salt bridges, voltmeters, etc.) in this portion of the experiment. Annotate on the schematic which side is the anode, which side is the cathode. the sign of each half cell, the composition of the metals and solutions, and the direction of the flow of the electrons through the cell. 2. Write the half reactions that occur at the anode and cathode in this electrochemical cell. Annotate which half reaction occurs at the anode and the cathode. 3. Write the overall balance reaction of this electrochemical cell.
