Published on 2018 July 26th

Set up and observe the spontaneous redox reaction that occurs between copper metal and silver nitrate solution when they are in direct contact. Then find out how this reaction can be used to generate an electric current. Set up the galvanic cell that utilizes this reaction and observe what happens at the anode and the cathode. Find out the principles behind the cell design. Determine the equation for the net cell reaction from the half-equations. Explain the changes observed. This learning object is one in a series of three learning objects.
1. Students set up a spontaneous redox reaction and a galvanic cell that utilizes this reaction.
2. Students explain their observations when an oxidant and a reductant are in direct contact, and when they are separated in a galvanic cell.
3. Students describe the basic principles behind the design of a galvanic cell and the processes that occur in the cell.
4. Students determine the equation for the net cell reaction from the half-equations and relate this to the equation for the reaction when the reactants are in direct contact.
