Electrochemistry

Electrochemistry deals with the relationship between the flow of electric current and chemical changes. It also deals with the conversion of chemical to electrical energy and electrical to chemical energy. The two main branches of electrochemistry are electrolysis and the electrochemical cell. During electrolysis, electrical energy is converted to chemical energy. During the operation of an electrochemical cell, the reverse takes place, chemical energy is converted to electrical energy.

The Buzzer Experiment

The Buzzer Experiment is an example of electrolysis. A more technical name for it would be "Electrolysis of a Concentrated Sodium Chloride Solution (Brine)". Kids for Chemistry breaks down the electrolysis of a Sodium Chloride solution into simpler terms and makes it much more easily understood. Unique patented drawings give students a visual picture of the atoms and molecules involved. And the animation provides a clear understanding of the mechanics behind the chemistry.

The chemical reaction for the electrolysis of sodium chloride solution is:

2H₂0 + 2NaCl  ----->  H₂ + Cl₂  +  2NaOH
