Description
Ferric ammonium sulfate A.R. (analytical reagent), also known as ferric alum, is a high-purity grade of ferric ammonium sulfate specifically formulated for analytical and laboratory applications. It shares the same chemical composition as regular ferric ammonium sulfate, consisting of iron(III) ions, ammonium ions, sulfate ions, and water molecules. Ferric ammonium sulfate A.R. is meticulously purified to ensure minimal impurities, making it suitable for precise and accurate analytical work, such as complexometric titrations, determination of phosphate ions, and qualitative analysis of metals. It is commonly used as a reagent in various chemical and analytical procedures.
