Science Fair Projects Electrolysis

Electrolysis process The electrolysis process is a chemical reaction that takes place in an electrolyte solution when electricity is passed through it. The electrolyte solution contains both positive and negative ions. The positive ions are called anions while the negative ions are known as cations.
