Product Overview

Zimmermann-Reinhard’s Reagent is an essential solution for precise quantitative chemical analysis, particularly in the titrimetric determination of iron(II) ions using potassium permanganate. This specialized reagent is formulated to overcome common interferences that can compromise the accuracy of such titrations. It primarily contains manganese(II) sulfate, phosphoric acid, and sulfuric acid, each playing a critical role in enhancing the reliability of results.

The manganese(II) sulfate component acts to reduce the oxidation of chloride ions, which are often present in samples and can react with permanganate, leading to erroneous measurements. Phosphoric acid serves a dual purpose: it complexes with the iron(III) ions formed during the titration, making them colorless and ensuring a sharp, unambiguous endpoint by preventing the yellow color of Fe(III) from masking the pink permanganate endpoint. Additionally, phosphoric acid lowers the redox potential of the Fe(III)/Fe(II) couple, making the oxidation of Fe(II) easier and more complete. Sulfuric acid maintains the acidic environment necessary for the permanganate titration to proceed effectively.

Our Zimmermann-Reinhard’s Reagent is meticulously prepared to analytical reagent (AR) grade standards, guaranteeing high purity and consistent performance. Its formulation ensures maximum precision and reproducibility, making it an indispensable tool for research laboratories, quality control facilities, and educational institutions across India. Rely on this reagent for accurate iron(II) determinations in diverse samples, contributing to robust and dependable analytical outcomes.
