Be sure to include a figure legend below each picture (please include the voltage and the metal solution being tested in the figure legend). • What is the function of a salt bridge in an electrochemical (or voltaic) cell? Explain in 2 – 3 sentences. Solve here: The function of a salt bridge is to maintain electrical neutrality inside the circuit of a cell. It acts as an electrical connection between two half cells and prevents di昀昀usion of solution from one cell to the other. • Define oxidation and reduction . In the electrochemical cells that you built, which process (oxidation or reduction) occurs at the anode ? At the cathode ?
