Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis, metals and gases may form at the electrodes.
Ionic substancesionic substance: Ionic substances form when a metal reacts with a non-metal. They contain charged particles called ions. contain charged particlescharged particle: A particle that carries an electric charge. called ions [ion: Positively- or negatively-charged particles - eg positively charged hydrogen, sodium and potassium atoms. Ion charge helps determine a substance's acidity or alkalinity ]. For example, lead bromide contains positively charged lead ions and negatively charged bromide ions.
Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them.
For electrolysis to work, the ions must be free to move. Ions are free to move when an ionic substance is dissolved in water or when melted. For example, if electricity is passed through moltenmolten: Molten means reduced to liquid form by heating. It is mainly used to describe rock, glass or metal. lead bromide, the lead bromide is broken down to form lead and bromine.
Here is what happens during electrolysis:
The substance that is broken down is called the electrolyteelectrolyte: An electrolyte is a substance which in solution will conduct an electric current..
