QUE SIGNIFIE COULOMETRIC EN ANGLAIS
Coulométrie
Coulometry est le nom donné à un groupe de techniques de chimie analytique qui déterminent la quantité de matière transformée lors d'une réaction d'électrolyse en mesurant la quantité d'électricité consommée ou produite. Il s'appelle Charles-Augustin de Coulomb. Il existe deux catégories de base de techniques coulométriques. La coulométrie potentiostatique implique de maintenir le potentiel électrique constant pendant la réaction à l'aide d'un potentiostat. L'autre, appelé titrage coulométrique ou coulométrie amperostatique, maintient le courant constant à l'aide d'un amperostat.
