Chemical Properties

Property Specification
Appearance Red crystalline powder
Solubility Soluble in water
pH (1% solution) Around 6.5–7.5
Stability Stable under normal temperature and pressure
Toxicity Low, but should be handled with care to avoid decomposition under acidic conditions

Safety and Handling

Although Potassium Ferricyanide is relatively stable, it should be stored in a cool, dry, and well-ventilated area away from strong acids and heat sources. When exposed to acids, it may release toxic hydrogen cyanide gas. Always wear appropriate personal protective equipment (PPE) such as gloves, goggles, and lab coats during handling.

Packaging and Storage

  • Packaging: 25 kg woven bags, fiber drums, or as customer requirements.

  • Storage: Store in tightly sealed containers. Keep away from sunlight and moisture.

Frequently Asked Questions (FAQ) — Potassium Ferricyanide CAS No.13746-66-2

1. What is Potassium Ferricyanide used for?

Potassium Ferricyanide is mainly used as an oxidizing agent in analytical chemistry, bleaching agent in photography, and reagent in electroplating and blueprinting. It helps in detecting iron ions and performing redox reactions in laboratories.

2. Is Potassium Ferricyanide toxic or dangerous?

Potassium Ferricyanide itself is not highly toxic under neutral conditions.
However, it can release toxic hydrogen cyanide gas if it comes into contact with acids or strong heat. Always handle with care, use gloves and goggles, and store in a cool, dry place away from acids.

3. How should Potassium Ferricyanide be stored?

Store in tightly sealed containers in a cool, dry, and ventilated area. Keep away from direct sunlight, moisture, and acidic materials. Proper storage maintains product stability and prevents decomposition.

4. What is the difference between Potassium Ferricyanide and Potassium Ferrocyanide?

Potassium Ferricyanide (K₃[Fe(CN)₆]) is the oxidized form, containing iron(III).
Potassium Ferrocyanide (K₄[Fe(CN)₆]) is the reduced form, containing iron(II).
Both are coordination compounds but have different chemical reactivity and uses in industrial and analytical processes.
