About Potassium Dichromate SQ 500G Qualigens

Potassium Dichromate (KCrO 7) is a bright, red-orange crystalline solid, a powerful oxidizing agent used in labs for titrations (oxidimetry/iodometry) and industrial processes (dyes, matches, wood treatment). It's a stable, non-deliquescent salt, but hazardous (hexavalent chromium), requiring careful handling (PPE, ventilation) due to its strong oxidizing nature, incompatibility with reducing agents, and potential for explosion when mixed with combustibles. Key Properties & Description

Appearance: Bright, red-orange crystalline solid.
Formula: KCrO 7.
Nature: Strong oxidizing agent, particularly in acidic media.
Solubility: Moderately soluble in water (less than chromic acid), insoluble in alcohol/acetone.
Stability: Chemically stable under standard conditions but decomposes on strong heating.

Common Uses (in 500g Lab/Industrial Grade)

Analytical Chemistry: Volumetric standard for titrations (e.g., iodometry).
Industrial: Manufacturing of dyes, fireworks, matches, pigments, wood preservatives, and as a catalyst.

Safety & Handling (SQ - Safety Grade)

Hazard: Contains hexavalent chromium, harmful to health and an oxidizer.
Precautions: Use in well-ventilated areas, wear PPE (gloves, eye protection), keep away from heat/sparks and combustible materials to prevent fire/explosion.
Storage: Store separately from incompatible substances.
