説明Chloric acid, HClO3, is an oxoacid of chloride, and the formal precursor of chlorate salts. It is a strong acid (pKa=-1) and a strong oxidizing agent. It is stable in cold aqueous solution up to a concentration of approximately 30%, and solution of up to 40% can be prepared by careful evaporation under reduced pressure. Above these concentrations, and on warming, chloric acid solutions decompose to give a variety of products, for example: 8HClO3→4HClO4+2H2O+2Cl2+3O2 Note that it disproportionates into perchloric acid in which the chlorine atom has a+7 oxidation state and also the zero oxidation state of chlorine gas (an oxidation–reduction reaction). Thus, under the proper conditions, it can also be used to make perchloric acid. 3HClO3→HClO4+H2O+2ClO2

使用用途塩素酸の関連物質である塩素酸ナトリウムは、EUにおいて環境への影響のため除草剤としての使用が2009年に禁止されています。 1. 酸化剤・漂白剤 塩素酸の水溶液は強酸であり、強い酸化力を持つ物質です。強力な漂白効果を有しており、パルプを始め様々な物質の漂白剤として工業的に利用されています。 また、多くの金属とその酸化物、水酸化物、炭酸塩を溶解させることで、塩素酸塩 (、、塩素酸アンモニウム、塩素酸亜鉛など) の原材料としても利用されています。 2. 火薬・爆薬 塩素酸の塩は、火薬や爆薬の原料としても使用されてきた歴史があります。純度98%の塩素酸ナトリウムが農薬として使用されていたこともありましたが、爆発の危険性が高く、また非合法の爆発物として利用される例が頻発して社会問題となりました。 これにより、1970年代以降はなどが配合された薬剤が主流となっています。

Self-reactive. Concentrations of CHLORIC ACID above 40% decompose [Mellor 2 Supp. 1:576 1956]. Antimony sulfide and concentrated solutions of chloric acid react with incandescence [Mellor Supp. II Part I:584 1956]. Arsenic sulfide and concentrated solutions of chloric acid react with incandescence. Reacts with vigor even explodes with other metal sulfides, i.e. copper sulfide [Mellor Supp. II Part I:584 1956]. In contact with oxidizable materials, including ammonia, reactions can be extremely violent. Filter paper ignites after soaking in chloric acid, [Mellor, 1946, Vol. 2, 310]. Explosions have been recorded by mixtures of chloric acid solution with metals such as: antimony, bismuth, and iron. This is due to the formation of explosive compounds including hydrogen.
