23 paź 2019 · This document provides instructions for estimating Fe (II) ions in a solution by titrating against a standard solution of potassium dichromate (K2Cr2O7) using diphenylamine as an internal indicator. The procedure involves preparing standard solutions of K2Cr2O7, sulfuric acid, and a Mohr's salt solution containing the unknown amount of Fe (II).
In this experiment you will use a standard solution of potassium dichromate (K 2 Cr 2 O 7) to determine the percent by weight of iron (as Fe 2+) in an unknown solid. Dichromate ion reduces to two chromium (III) ions.
