HypochloriteIn chemistry, hypochlorite, or chloroxide is an anion with the chemical formula ClO−. It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). The Cl-O distance in ClO− is 1.69 Å. The name can also refer to esters of hypochlorous acid, namely organic compounds with a ClO– group covalently bound to the rest of the molecule.
Ionic compoundIn chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic species such as the ammonium (NH4+) and carbonate (CO32−) ions in ammonium carbonate.
Réaction acido-basiqueUne réaction acido-basique ou réaction acide-base est une réaction chimique au cours de laquelle un corps chimique ou entité dite « acide » réagit avec une entité dite « basique » et nommée base. Dans le cas des solvants protiques, en particulier les solutions aqueuses, il se produit un transfert d'un ou plusieurs ions H de l'acide vers la base. La notion de couple acide-base date de 1920, puisqu'elle ne peut apparaître qu'après la définition commune du proton.
