Chlorid titration
WebChloride ions accelerate the corrosion of iron, as is all too familiar to anyone who drives a car on roads that are de-iced with road salt (mainly sodium chloride). Removing the chloride ions is an important step for conservators in treating chloride-contaminated objects. ... Another more accurate way is to carry out a titration with silver ... WebResidual Titrations— Some Pharmacopeial assays require the addition of a measured volume of a volumetric solution, in excess of the amount actually needed to react with the substance being assayed, the excess of this solution then being titrated with a second volumetric solution. This constitutes a residual titration and is known also as a “back …
