Electrode potentials, cells and corrosion

Publisher Summary

This chapter focuses on electrode potentials, cells, and corrosion. A metal is called half-cell when it comes in contact with a solution of its ions, and the potential difference of the half-cell is called the electrode potential of the half-cell. The symbol denoting the electrode potential is E, and the quantity is measured in volts. The electrode potential of a half-cell cannot be determined independently, but is measured by placing it in series with a different half-cell. These are joined together by a salt bridge, and a voltmeter is connected across the complete circuit to measure the voltage produced. A battery is a combination of more than one cell. The cells in a battery ...
