The perchlorates of lithium, calcium, and barium have high solubility in water; the perchlorates of potassium, rubidium, cesium, and ammonium are insoluble in cold water but soluble in hot water. Silver perchlorate is soluble in both water and toluene as well as pyridine. Barium perchlorate and magnesium perchlorate possess strong dehydrating properties and can be used as efficient dehydrants. Solid perchlorates are strong oxidizing agents at high temperatures. When potassium perchlorate is heated to 656°C, it melts and decomposes into potassium chloride and oxygen; it can cause combustion when in contact with flammable materials or oxidizers. Ammonium perchlorate can provide the oxygen required for high-energy fuels. When it reacts with flammable substances, it produces a large amount of gas, and it is used as a propellant for rockets.
