• Voltaic Cell

• A standard cell comprising of two half-cells: zinc metal electrode in 1.0 M ZnSO 4 solution, a copper metal electrode in a 1.0 M CuSO 4 solution, and a connecting salt bridge. The cell reaction is Zn(s) + Cu 2 + (aq) - Zn 2 + (aq) + Cu(s). The electrodes are connected to a voltmeter.

• Is this a spontaneous or non-spontaneous reaction? What is the oxidation half-reaction that occurs and where does it occur?

Now that we have observed various electrochemical processes, we need a convention to describe each voltaic cell. 20.3 Silver-Copper Voltaic Cell Part 1. 20.3 Silver-Copper Voltaic Cell Part 2. 20.3 Silver-Iron Voltaic Cell. When you describe voltaic cells, be sure to keep a few things in mind.
