Berthollet’s salt – potassium chlorate KClO3.
Berthollet’s salt is extracted by the interaction of chlorine with potassium hydroxide: 3Cl2 + 6KOH = 5KCl + KClO3 + 3H2O.
This salt contains a lot of oxygen and therefore gives it up quite easily; the reaction takes place when heated:
2KClO3 = 2KCl + 3O2 – thus it is possible to obtain potassium chloride from potassium chlorate.
