Berthollet, along with Antoine Lavoisier and others, devised a chemical nomenclature, or a system of names, which serves as the basis of the modern system of naming chemical compounds. He also carried out research into dyes and bleaches (introducing the use of chlorine as a bleach) and determined the composition of ammonia. Berthollet was one of the first chemists to recognize the characteristics of a reverse reaction, and hence, chemical equilibrium. Potassium Chlorate (KClO3), a strong oxidizer, is known as Berthollet's Salt. Non-stoichiometric compounds are also named berthollides in his honor. Antoine-Laurent de Lavoisier (August 26, 1743 – May 8, 1794) the father of modern chemistry, was a French nobleman prominent in the histories of chemistry, finance, biology, and economics. ...
