Mohr's salt, scientifically known as Ammonium Iron(II) Sulfate (CAS 10045-89-3), is a staple in chemistry laboratories worldwide, renowned for its stability as a source of ferrous ions. This double salt of ferrous sulfate and ammonium sulfate offers distinct advantages over simple ferrous salts, making it indispensable for various analytical and research applications. As a supplier committed to chemical education and industry needs, understanding Mohr's salt is fundamental.

The chemical formula for Mohr's salt is typically represented as (NH4)2Fe(SO4)2·6H2O. Its defining characteristic is its resistance to oxidation by atmospheric oxygen, a property that stems from its crystalline structure. Unlike ferrous sulfate, which readily oxidizes to ferric ions, Mohr's salt solutions remain stable for extended periods. This stability is crucial for accurate titrations and maintaining the integrity of prepared solutions. When you buy Ammonium Iron(II) Sulfate, you are purchasing a reliable chemical standard.

The preparation of Mohr's salt in a laboratory setting involves carefully dissolving equimolar amounts of hydrated ferrous sulfate and ammonium sulfate in a dilute sulfuric acid solution, followed by crystallization. The dilute sulfuric acid is essential to prevent the hydrolysis of ferrous ions and to maintain an acidic environment that further inhibits oxidation. This process ensures the formation of the characteristic light green crystalline solid that is easily identifiable.

In terms of applications, Mohr's salt is primarily utilized as a primary standard in quantitative analysis, particularly in redox titrations. It is used to standardize oxidizing agents like potassium permanganate, enabling precise determination of unknown concentrations. Its clarity and stability in solution contribute to sharper endpoint detection, which is vital for accurate analytical results. For any laboratory needing a dependable ferrous ion source, purchasing high-purity Mohr's salt from a trusted manufacturer is paramount.

Beyond titrations, it finds use in specific colorimetric assays and as a component in some specialized chemical formulations. Its consistent performance makes it a valuable reagent for researchers and students alike. If you are looking to purchase Ammonium Iron(II) Sulfate for your laboratory or industrial needs, choosing a reputable supplier ensures you receive a product that meets the rigorous demands of chemical analysis.
