What is Ferric Nitrate CAS No.10421-48-4?

Ferric Nitrate – Aozun Yazhou Chemical, with the chemical formula Fe(NO3)3, is a salt formed by the reaction of nitric acid (HNO3) with iron(III) hydroxide (Fe(OH)3). It typically exists as a pale violet, green, or grayish-white crystalline solid.

Unpacking the Chemical Makeup and Structure

Ferric nitrate boasts a relatively simple yet effective structure. Each molecule consists of one iron(III) cation (Fe3+) surrounded by three nitrate anions (NO3-). These oppositely charged ions are attracted to each other through electrostatic forces, forming a stable ionic compound.

Physical Appearance and Properties

Imagine a lumpy crystal resembling coarse salt, but with a subtle violet, green, or grayish-white hue. That’s ferric nitrate in its solid form. Interestingly, it readily dissolves in water, making it a valuable water-soluble salt.

Safety Considerations When Handling Ferric Nitrate

While ferric nitrate isn’t inherently explosive, it’s crucial to handle it with care. Here’s why:

  • Potential Hazards:

    • Oxidizing Agent: Ferric nitrate can accelerate the burning of combustible materials.
    • Irritant: It can irritate the skin, eyes, and respiratory system upon contact or inhalation.

  • Safe Handling Practices:

    • Wear appropriate personal protective equipment (PPE) like gloves, goggles, and a respirator when handling ferric nitrate.
    • Work in a well-ventilated area to avoid inhalation.
    • Keep it away from heat sources and flammable materials.
    • Always follow proper safety protocols and consult the safety data sheet (SDS) for specific handling guidelines.

Applications of Ferric Nitrate: A Spectrum of Uses

Ferric nitrate’s unique properties translate into a diverse range of applications across various industries. Let’s explore some of its key uses:

Water Treatment: Cleaning Up Our Water Supply

Ferric nitrate plays a vital role in water treatment, particularly in the process of coagulation and flocculation.

  • Coagulation: Ferric nitrate introduces positively charged ions into the water. These ions attract negatively charged suspended particles like dirt, clay, and bacteria.
  • Flocculation: The aggregated particles, now larger and heavier, clump together and settle out of the water, making it easier for removal through filtration.

This process helps to purify raw water, making it safe for drinking and industrial applications.

Ferric Nitrate CAS No.10421-48-4 Pigment Production: Adding Vibrancy to Our World

Ferric nitrate is a crucial component in the production of various pigments, including:

  • Iron oxide pigments: These pigments, like rust-colored iron(III) oxide (Fe2O3), offer a range of hues from yellow to red and are used in paints, ceramics, and plastics.
  • Prussian blue: This vibrant blue pigment finds applications in paints, inks, and even textiles.
