About this document
Glycerin Determination via Dichromate Method by ScribdTranslations is a document available to read on EtoBox.
This document describes a method to determine the amount of glycerin in a sample through a potentiometric titration using potassium dichromate. The glycerin sample is completely oxidized with excess dichromate to carbon dioxide and water. Then, the excess dichromate is reduced with iron and ammonium sulfate and is potentiometrically titrated with a standard dichromate solution. The titration curve allows for locating the equivalence point and calculating the amount of glycerin.
