Un hydroxyde est un sel métallique de formule générique (Me(OH)n, comme NaOH, KOH, Ca(OH)2, Al(OH)3...), constitué d'un cation métallique et d'un ou de plusieurs anions hydroxydes. L'anion hydroxyde (ou hydroxyle) se réfère à l'ion OH . C'est un des ions polyatomiques les plus simples constitué d'un atome d'oxygène et d'un atome d'hydrogène. Il est porteur d'une seule charge électrique négative centrée sur l'atome d'oxygène. Cet anion est basique car il peut acce… WebThe concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes, and specific vocabulary has …
