That application started soon after French chemist Labarraque discovered those properties, around 1820 (still before Pasteur formulated his germ theory of disease). Les hypochlorites se décomposent également sous l'effet de la lumière en donnant des chlorures et de l'oxygène O2. L'acide hypochloreux est un acide faible (pKa d'environ 7,5), ce qui signifie qu'il se dissocie légèrement en les ions hydrogène et hypochlorite comme indiqué dans l'équation: : HOCl ⇌ H+ + OCl- Entre un pH de 6,5 et 8,5, cette dissociation est … It is unstable, meaning that it breaks down easily. Hypochlorite is an ion. , Osaka, Japan) in our laboratory with normal tap water on the day of use. Cette instabilité se manifeste par la dismutation des hypochlorites en oxygène O2, chlorure Cl− et chlorate ClO3− : Un article de Wikipédia, l'encyclopédie libre. [17] The same study found that low (micromolar) hypochlorite levels induce E. coli and Vibrio cholerae to activate a protective mechanism, although its implications were not clear.
