Perchlorates are the salts derived from perchloric acid—in particular when referencing the polyatomic anions found in solution, perchlorate is often written with the formula . Though produced by natural processes, the preponderance of perchlorates on Earth are produced commercially. Perchlorate salts are mainly used for propellants, exploiting properties as powerful oxidizing agents. Perchlorate contamination in the environment has been extensively studied as it has effects on human health. Perchlorate has been linked to its negative influence on the thyroid gland.
Most perchlorates are colorless solids that are soluble in water, except for potassium perchlorate, which has the lowest solubility of any alkali metal perchlorate (1.5 g in 100 ml of water at 25 °C). Four perchlorates are of primary commercial interest: ammonium perchlorate (NHClO), perchloric acid (HClO), potassium perchlorate (KClO), and sodium perchlorate (NaClO). Perchlorate is the anion resulting from the dissociation of perchloric acid and its salts upon their dissolution in water. Except for potassium perchlorate, perchlorate salts are soluble in water and dissociate into the perchlorate anion and the cation from the salt. Because perchlorate salts are readily soluble in both aqueous and non-aqueous solutions, when these salts are solvated, especially ammonium perchlorate, they can undergo redox reactions and release gaseous products and contaminate water and soil.
Usage examples of "perchlorate".
For example, Iraq built a facility for the production of ammonium perchlorate, a key ingredient in solid missile propellant, indicating that work continues on advanced solid-fuel multistage missiles.
An early mixture of magnesium and perchlorate of potash has since given way to an even slower-burning mix of aluminum powder and potassium permanganate which will probably remain standard until the last Musky has been slain.
