Ammonium Dichromate Crystal – 500 gram Packs

Ammonium Dichromate Crystal is an inorganic chromium(VI) salt with the chemical formula (NH₄)₂Cr₂O₇. Also known as ammonium bichromate, it consists of ammonium ions and dichromate ions and occurs as a bright orange-red crystalline solid. It is water-soluble and exhibits strong oxidizing properties, making it relevant to selected inorganic chemistry investigations, oxidation-reduction studies, and specialized analytical procedures. Its characteristic decomposition behaviour has also been examined in controlled chemical demonstrations and research. Ammonium Dichromate requires exceptional care because it contains hexavalent chromium, which presents serious health hazards, including carcinogenicity, and can cause significant environmental harm. It is not appropriate for routine school experiments or unsupervised demonstrations. Laboratory use should be restricted to authorized, appropriately equipped facilities with trained personnel, suitable containment, and compliant hazardous-waste management. This 500 gram pack format is intended for laboratory procurement where the specific reagent is required and its use is appropriately authorized.

What is the CAS number of Ammonium Dichromate?

The CAS Registry Number for Ammonium Dichromate is 7789-09-5. This identifier distinguishes it from related chromium compounds, including Ammonium Chromate, which has a different formula and CAS number. Confirm the identifier when checking inventory records, technical documentation, and applicable hazardous-substance requirements.

Is Ammonium Dichromate suitable for school and research laboratories?

Ammonium Dichromate is not suitable for routine school practicals or unsupervised demonstrations because it is a strong oxidizer and a hazardous chromium(VI) compound associated with cancer and other serious health effects. Its use should be limited to authorized research or analytical facilities with trained personnel, suitable containment, and a documented risk assessment.

How should Ammonium Dichromate be stored and handled safely?

Store it in a compatible, tightly closed, clearly labelled container in a cool, dry, secure area designated for appropriate oxidizing hazardous chemicals. Keep it away from combustible materials, organic substances, reducing agents, and incompatible chemicals. Prevent dust exposure and environmental release, and follow the current Safety Data Sheet and institutional hazardous-waste procedures.

Storage Conditions for Ammonium Dichromate

Store Ammonium Dichromate in a compatible, tightly closed, clearly labelled container in a cool, dry, well-ventilated and access-controlled area designated for oxidizing hazardous chemicals. Segregate it from combustible substances, organic materials, reducing agents, and other incompatible chemicals. Protect it from excessive heat, contamination, and uncontrolled access. Follow the applicable Safety Data Sheet and local requirements for storage of chromium(VI) compounds.

Precautions for Handling Ammonium Dichromate

Review the current Safety Data Sheet and complete a documented risk assessment before handling. Ammonium Dichromate is a strong oxidizer and a serious health hazard associated with carcinogenicity, respiratory sensitization, and environmental toxicity. Handling must be restricted to trained personnel using appropriate containment, suitable chemical-resistant gloves, protective clothing, and eye protection. Avoid all dust exposure and skin contact, prevent release to drains, and collect residues as hazardous waste under applicable regulations. Never heat or mix the substance with combustible or reducing materials outside an approved, specifically assessed procedure.
