Description
Ferrous ammonium sulfate, also known as ammonium iron(II) sulfate or Mohr’s salt, is a double salt composed of ferrous ions (iron(II)) and ammonium ions, along with sulphate ions. It is typically found as a pale green crystalline solid. Ferrous ammonium sulfate is commonly used in analytical chemistry as a reducing agent and as a primary standard for standardizing solutions of oxidizing agents. It is also employed in various laboratory applications, including in the synthesis of coordination compounds and as a reagent in chemical reactions. Additionally, ferrous ammonium sulfate finds uses in photography, water treatment, and as a nutrient source in agriculture.
