Claude Louis Berthollet

Claude Louis Berthollet (9 December 1748 Talloires, France – 6 November 1822 Arcueil,France) was a Savoyard-French chemist who became vice president of the French Senate in 1804.[1] He is known for his scientific contributions to theory of chemical equilibria via the mechanism of reverse chemical reactions, and for his contribution to modern chemical nomenclature. On a practical basis, Berthollet was the first to demonstrate the bleaching action of chlorine gas, and was first to develop a solution of sodium hypochlorite as a modern bleaching agent.
