1 mar 2018 · This work aims to present the international comparison results, as well as the studies needed to develop a certified reference material (CRM) of K2Cr2O7 for redox titrations.
We evaluated several literature-based replacement oxidants for K2Cr2O7 (potassium dichromate) and identified KIO3 (potassium iodate) as the only chemically viable alternative for thiosulfate standardizations, consistent with use of iodate by others.

Experiment-No-7 - Free download as PDF File (.pdf), Text File (.txt) or read online for free. The document describes an experiment to determine the concentration of a ferrous ammonium sulfate (FAS) solution using potentiometric titration with a standard potassium dichromate (K2Cr2O7) solution.
Molarity of FAS solution = [V K2Cr2O7 ×0.1] / (V FAS) Where: VK2Cr2O7 = volume of K 2Cr 2O7 (mL); VFAS = volume of FAS (mL) PROCEDURE: 1. Wash culture tubes and caps with 20% H 2SO 4 before using to prevent contamination. 2. Place sample (2.5 mL) in culture tube and Add K2Cr 2O7 digestion solution (1.5 mL). 3.
Journal of Analytical & Pharmaceutical Research Physicochemical Study of Potassium Dichromate (K2Cr2O7) in 10% Sucrose-Water at Different Temperature Research Article Abstract The knowledge of ion-solvent interaction by the help of volumetric and other fundamental properties has great importance and data generated from these experiments used ...
