In a voltaic cell what is the anode
WebThe electrode of an oxidation cell is called the anode. In this example the anode is zinc. As the reaction occurs, electrons leave the zinc metal in the anode, converting it to zinc ions. These ions then enter the solution, in this case zinc sulfate. The counterion doesn’t matter, as long as it’s soluble with the anode metal ion. WebVoltaic Cells A Voltaic cell is a device which physically separates the reduction half of a redox reaction from the oxidation half and results in a flow of electrons through the circuit. Each compartment of a voltaic cell is termed a half-cell. The half-cell that serves as the site for reduction contains the cathode electrode,
