Applications & Uses
- Analytical Chemistry & Titrations: Standard oxidizing reagent in Iodometry and other redox protocols.
- Laboratory Research: For preparation of reference solutions, calibration, or chemical synthesis requiring strong oxidizers.
- Industrial Processes: Used in leather tanning, textile dyeing, metal finishing, and corrosion control.
- Educational Purposes: Demonstration of oxidation‑reduction, colorimetric assays in chemistry teaching labs.
Safety, Handling & Hazards
Because Potassium Dichromate is a hexavalent chromium compound, it poses serious health and environmental risks:
- Hazardous Properties: Carcinogenic; causes severe skin burns and eye damage; toxic by inhalation and ingestion; very toxic to aquatic life.
- Protective Measures: Use gloves, goggles, and protective clothing. Work in a fume hood. Avoid inhalation of dust.
- Disposal: Follow local hazardous waste regulations. Do not release into the environment. Neutralize properly before disposal.
- Storage: Keep in a cool, dry place; ensure container is tightly sealed. Avoid humidity and incompatible materials (e.g., organic matter, reducing agents).
