Perchloric acid is a mineral acid with the formula HClO4. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric and nitric acid. It is a powerful oxidizer when hot, but its aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties. Perchloric acid is useful for preparing perchlorate salts, especially ammonium perchlorate, an important rocket fuel component. Perchloric acid is dangerously corrosive and readily forms potentially explosive mixtures.

  • Perchloric acid is a mineral acid with the formula HClO4. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric and nitric acid. It is a powerful oxidizer when hot, but its aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties.

  • Perchlorsäure, HClO4, ist eine Sauerstoffsäure des Chlors. Ihre Salze heißen Perchlorate.
  • Ácido perclórico es la denominación que se le otorga al ácido que resulta de la unión del óxido perclórico con H2O. Recibe tal nombre debido a que el cloro actúa con el estado de oxidación +7, que es el mayor de los cinco que posee (−1, +1, +3, +5 y +7). Es un ácido muy fuerte que tiene la magnitud más baja de pKa de los ácidos, por lo que en disolución acuosa se disocia totalmente. Es altamente corrosivo, y a concentraciones superiores al 72% es inestable y puede resultar explosivo, por lo que se deben tomar precauciones a manipularlo.
  • L’acide perchlorique est un composé chimique de formule HClO4, où l'atome de chlore est à l'état d'oxydation +VII. C'est un oxoacide dont la force est comparable à celle d'acides forts tels que l'acide nitrique et l'acide sulfurique, ainsi qu'un agent oxydant. Il est utilisé notamment pour produire des perchlorates, principalement le perchlorate d'ammonium, qui entre dans la composition de propergols solides très utilisés en astronautique, notamment le PCPA. L'acide perchlorique est très corrosif et forme facilement des mélanges explosifs.
  • 過塩素酸(かえんそさん、英: perchloric acid)とは、塩素のオキソ酸の一種で、化学式 HClO4 と表される過ハロゲン酸。水に溶けやすい無色の液体。酸化数7価の塩素に、ヒドロキシ基(-OH)1個とオキソ基(=O)3個が結びついた構造を持つ。 塩素酸より酸素が1個多く、名称に「過/per」と付いているものの分子内に -O-O- 結合はなく本来の塩素原子の最高酸化状態であり過酸ではない。
  • Waterstofperchloraat of perchloorzuur (HClO4) is een sterk zuur in water. Het behoort tot de groep der halogeenzuurstofzuren. Waterstofperchloraat wordt doorgaans verkocht en gebruikt als oplossing in water.
  • Kwas nadchlorowy, HClO4 (nazwa Stocka: kwas chlorowy(VII)) – nieorganiczny związek chemiczny, jeden z najsilniejszych kwasów tlenowych. Chlor znajduje się w nim na VII stopniu utlenienia; jest to najtrwalszy kwas tlenowy tego pierwiastka. Jego bezwodnikiem jest tlenek chloru(VII), Cl2O7.
  • Хлорная кислота — одноосновная кислота, одна из самых сильных (в водном растворе, pK = ~ -10), безводная — исключительно сильный окислитель, так как содержит хлор в высшей степени окисления +7.
  • 高氯酸又名过氯酸,化学式为HClO4,是一種強酸,有强烈的腐蚀性、刺激性,通常以无色水溶液的形式存在。高氯酸的酸酐为Cl2O7。高氯酸的酸性强于硫酸、硝酸。热的高氯酸是一种极强的氧化剂,与有机物、还原剂、易燃物(如硫、磷等)接触或混合时有引起燃烧爆炸的危险,但室温下70%以下浓度的高氯酸相对稳定一些。高氯酸常被用来制备一些高氯酸盐,例如火箭燃料的重要成分——高氯酸铵。总而言之,高氯酸具有相当强的腐蚀性和危险性,并且极易形成易爆炸的混合物。
  • L'acido perclorico è un acido estremamente forte, altamente corrosivo e ossidante (in soluzione concentrata). È l'ossiacido del cloro allo stato di ossidazione + 7. A temperatura ambiente è un liquido incolore, dall'odore pungente. In concentrazioni superiori al 72% tende facilmente a esplodere; è per questo motivo che è difficile da ottenere puro e viene pertanto commercializzato in forma di soluzione acquosa concentrata fino al 70%. In queste condizioni l'acido perclorico è presente come monoidrato: HClO4 • H2O → [H3O]+ + [ClO4]− 3 HClO4 → [H3O]+ + [ClO4]− + Cl2O7
  • Ácido perclórico, HClO4, é um oxiácido do cloro e é um líquido oleoso incolor solúvel em água de odor pungente. É o oxiácido do cloro no estado de oxidação + 7. Em concentração superior a 72% tende facilmente a explodir: é por este motivo que dificilmente é obtível puro e é portanto comercializado na forma de solução aquosa concentrada no máximo a 70%.
