Chemistry Form 4: Chapter 6 - Constructing Electrochemical Series based on the Potential Difference between Two Metals

• In a voltaic cell, two different metals are used to create a potential difference.
• A higher metal in the electrochemical series will be made negative terminal.
• A lower metal in the electrochemical series will be made positive terminal.
• Conversion of energy is chemical energy to electrical energy.

Metals which are further apart in the electrochemical series produce a higher voltage than metals which are close to each other.

 By arranging the metals in order of their voltage readings, you can build up the electrochemical series.
