  Définition

  A salt of perchloric acid HClO₄, in which chlorine has a valence of +7. The most common perchlorate is sodium perchlorate, NaClO₄, a colorless crystalline solid salt, m.p. 482 °C (900 °F), soluble in water, and a powerful oxidizing agent. It is produced by the electrolysis of sodium chlorate in a cell with platinum anodes and steel cathodes, the resulting sodium perchlorate being separated from the residual sodium chlorate by fractional crystallization.

  Note :

  It is used in some explosives and is the source of perchloric acid and other perchlorates, such as ammonium perchlorate, NH₄ClO₄, used in solid jet propulsion compositions. While the most stable of the positive chlorine compounds, it is a dangerous fire and explosion risk when in contact with reducing and organic materials and with acids. It is moderately toxic.
