For procurement managers, R&D scientists, and formulation chemists in the chemical industry, a thorough understanding of product properties and safe handling is essential. Ferric sulfate, a widely used inorganic chemical, is no exception. This article details the key chemical properties and safe handling guidelines for ferric sulfate, ensuring informed procurement and application. NINGBO INNO PHARMCHEM CO.,LTD., as a premier manufacturer and supplier, prioritizes providing this crucial information to its clients.

Chemical Identity and Formula

Ferric sulfate, also known as iron(III) sulfate, is an inorganic compound with the chemical formula Fe₂(SO₄)₃. It is often encountered in its hydrated form, Fe₂(SO₄)₃·xH₂O, where 'x' typically ranges from 5 to 7, indicating a variable number of water molecules incorporated into its crystal structure. This compound is known for its acidic nature, a characteristic that is important in many of its applications.

Key Physical and Chemical Properties

Understanding the properties of ferric sulfate is key to its effective application and safe handling:

  • Appearance: Typically a yellow or reddish-brown powder.
  • Solubility: Readily soluble in water, forming an acidic solution.
  • Acidity: The aqueous solution exhibits acidic properties due to hydrolysis.
  • Fe3+ Content: High Fe3+ content is a defining characteristic, contributing to its effectiveness as a coagulant and oxidizing agent. For example, our product typically has a Fe3+ content of over 21.0% (m/m).
  • Reduced Matter (Fe2+): The presence of Fe2+ is usually minimal, with specifications often limiting it to 0.10% max.
  • Water Insoluble Material: High-purity ferric sulfate has very low water-insoluble content, often less than 0.3%, ensuring efficient dissolution and minimal residue.
  • pH Value: A 1% aqueous solution typically has a pH between 2 and 3.
  • Stability: It is a stable compound under normal storage conditions.

Applications Driven by Properties

These properties make ferric sulfate invaluable in various sectors:

  • Water Treatment: As a powerful coagulant and flocculant, it removes turbidity, COD, BOD, heavy metals, and phosphorus from drinking water and wastewater.
  • Mining: Used as an oxidizing agent in leaching processes and for treating mine water effluent.
  • Other Industrial Uses: Applications extend to pigments, photography, and etching.

Safe Handling and Storage Recommendations

While ferric sulfate is a vital industrial chemical, proper safety precautions are necessary:

  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves, eye protection (safety goggles or face shield), and protective clothing, as it can be irritating to skin and eyes.
  • Ventilation: Handle in a well-ventilated area to avoid inhaling dust or mists.
  • Incompatibilities: Keep away from strong bases, combustible materials, and other incompatible substances.
  • Storage: Store in a cool, dry, well-ventilated place in tightly sealed containers. Protect from moisture, as it is hygroscopic. Keep away from incompatible materials.
