L'ion phosphate (ou orthophosphate) est un anion polyatomique de formule chimique brute PO4 et de masse moléculaire de 94,97 daltons. Il se présente sous la forme d'un tétraèdre dont les sommets sont formés par les quatre atomes d'oxygène encadrant un atome de phosphore. Cet ion, qui comporte trois charges négatives, est la base conjuguée de l'ion hydrogénophosphate HPO4 (ou phosphate inorganique , noté « Pi ») qui est lui-même la base conjuguée de l'ion dihy… WebCalcium (Ca) and magnesium (Mg) are the most abundant alkaline-earth metal ions in nature, and their interaction with ferrihydrite (Fh) affects the geochemical cycling of …
