Calcium Chromate – 500 gram Packs

Calcium Chromate is an inorganic chromium(VI) compound with the chemical formula CaCrO₄. It is generally described as a yellow solid and consists of calcium ions and chromate ions, with chromium in the +6 oxidation state. Its oxidizing behaviour and characteristic chromate chemistry make it relevant to specialized inorganic chemistry research, investigations of chromium compounds, and selected materials studies. Calcium Chromate Laboratory Reagent should be considered only for procedures that specifically require this compound and can accommodate its significant health and environmental hazards. Hexavalent chromium compounds are associated with serious toxicological risks, including carcinogenicity, so appropriate containment, trained personnel, and regulated waste-management practices are essential. Before purchasing or using Calcium Chromate, laboratories should confirm the exact chemical form, product specifications, applicable regulatory requirements, and current safety documentation. Its use in educational settings requires particular caution and a documented risk assessment.

Frequently Asked Questions About Calcium Chromate

What is Calcium Chromate used for in laboratories?

Calcium Chromate is associated with specialized inorganic chemistry research involving chromate compounds, chromium(VI) reactions, and selected materials investigations. Its use requires stringent safety and environmental controls because of its toxicological hazards. Less hazardous alternatives should be considered wherever they can meet the scientific objective.

What is the chemical formula and molecular weight of Calcium Chromate?

The formula of anhydrous Calcium Chromate is CaCrO₄, and its formula mass is approximately 156.07 g/mol. This value applies to the anhydrous compound. Any hydrated form has a different formula mass, so the exact chemical identity must be confirmed before performing laboratory calculations.

What is the CAS number of Calcium Chromate?

The CAS Registry Number commonly associated with anhydrous Calcium Chromate is 13765-19-0. Confirm the identifier against the exact chemical form and supplier documentation before procurement. Correct identification is particularly important for chromium(VI) compounds because their handling, regulatory requirements, and waste-management procedures require careful consideration.

Is Calcium Chromate suitable for school and college laboratories?

Calcium Chromate is not suitable for routine school practicals or unsupervised student experiments because chromium(VI) compounds present serious health hazards, including carcinogenicity. Any institutional use requires a documented risk assessment, suitable containment, trained personnel, and compliant waste disposal. Safer alternatives should be preferred when scientifically appropriate.

How should Calcium Chromate be stored and handled safely?

Store Calcium Chromate in a compatible, tightly closed, clearly labelled container in a secure, dry area. Segregate it from combustible materials, organic substances, reducing agents, and other incompatible chemicals. Prevent dust formation and environmental release, use appropriate containment and protective equipment, and follow the current Safety Data Sheet and institutional hazardous-waste procedures.

Storage Conditions for Calcium Chromate

Store Calcium Chromate in a tightly closed, compatible, clearly labelled container in a dry, secure, appropriately ventilated area. Keep it segregated from combustible materials, organic substances, reducing agents, and other incompatible chemicals. Restrict access to authorized personnel and prevent contamination or release into drains, soil, and waterways. Follow the applicable Safety Data Sheet and institutional storage requirements.

Precautions for Handling Calcium Chromate

Review the current Safety Data Sheet and complete a documented risk assessment before handling Calcium Chromate. Chromium(VI) compounds present serious carcinogenic, toxicological, and environmental hazards. Use closed-system handling or effective local exhaust ventilation, suitable chemical-resistant gloves, protective clothing, and appropriate eye and face protection. Avoid dust generation and all unnecessary exposure. Keep the material away from incompatible substances and follow approved spill-response and hazardous-waste procedures. Handling should be restricted to trained personnel in appropriately equipped facilities.
