Calcium Chromate- 1 Kg Packs

Calcium Chromate is an inorganic calcium salt of chromic acid, containing chromium in the +6 oxidation state. Its chemical formula is CaCrO₄, and its formula mass is approximately 156.07 g/mol. The compound is generally encountered as a yellow solid and exhibits oxidizing properties, making its chemical reactivity and safety requirements important considerations in laboratory work. Calcium Chromate is relevant to specialized inorganic chemistry investigations, chromate chemistry, and research involving oxidation-reduction reactions and the behaviour of chromium compounds. Its use in educational, analytical, or research laboratories must be restricted to appropriate procedures with suitable containment, trained personnel, and applicable institutional controls. Hexavalent chromium compounds present serious health and environmental hazards, including carcinogenicity. The correct chemical form, reagent specifications, and safety documentation should therefore be reviewed before procurement or use. This reagent is not suitable for routine student practicals without a specific risk assessment and appropriate controls.

Why Choose Lab Wale to Buy Calcium Chromate

Lab Wale provides a sourcing option for laboratory chemicals and scientific supplies for research institutions, universities, and laboratory professionals. When considering Calcium Chromate, purchasers should verify the exact chemical identity, stated grade, applicable specifications, pack size, and available safety documentation before ordering. Because this compound contains hexavalent chromium, procurement should be limited to legitimate, authorized laboratory applications with appropriate risk controls, trained personnel, and compliant storage and waste-management arrangements.

Frequently Asked Questions About Calcium Chromate

What is Calcium Chromate used for in laboratories?

Calcium Chromate is relevant to specialized inorganic chemistry research involving chromate compounds, chromium(VI) reactions, and selected materials investigations. Its use requires stringent controls because of its oxidizing properties, carcinogenic hazards, and environmental toxicity. Less hazardous alternatives should be considered whenever they can achieve the scientific objective.

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

The chemical formula of anhydrous Calcium Chromate is CaCrO₄, and its formula mass is approximately 156.07 g/mol. Calcium chromate can also occur in hydrated forms, which have different formula masses. The exact chemical form must be confirmed before using the molecular weight in calculations or experimental procedures.

What is the CAS number of Calcium Chromate?

The CAS Registry Number for anhydrous Calcium Chromate is 13765-19-0. This identifier corresponds to CaCrO₄. Hydrated forms may have different identifiers, so the chemical formula, hydration state, and supplier specifications should be checked together when selecting the correct material.

Is Calcium Chromate suitable for school and college laboratories?

Calcium Chromate is not appropriate for routine school practicals or unsupervised student experiments because hexavalent chromium compounds can cause cancer and serious health effects. Its use should be restricted to appropriately equipped facilities where trained personnel, documented risk assessments, exposure controls, and compliant waste-management procedures are in place.

What precautions are required when handling Calcium Chromate?

Calcium Chromate requires strict exposure prevention. Avoid all dust generation and contact, use suitable protective equipment and effective local exhaust or closed-system containment, and keep it away from combustible materials and reducing agents. Store it securely, prevent environmental release, and follow the current Safety Data Sheet and institutional hazardous-waste procedures.

Storage Conditions for Calcium Chromate

Store Calcium Chromate in a tightly closed, clearly labelled, compatible container in a dry, secure, well-controlled area. Protect it from moisture and keep it segregated from combustible substances, organic materials, reducing agents, and other incompatible chemicals. Prevent access by unauthorized personnel and ensure that storage and spill containment prevent release into drains, soil, or waterways.

Precautions for Handling Calcium Chromate

Review the current Safety Data Sheet and complete a documented risk assessment before handling Calcium Chromate. Hexavalent chromium presents serious carcinogenic, toxic, corrosive, and environmental hazards. Use closed-system handling or effective local exhaust ventilation, appropriate chemical-resistant gloves, protective clothing, and suitable eye and face protection. Prevent dust formation and all unnecessary exposure. Keep the compound away from combustible and reducing materials, and use approved hazardous-waste procedures. Handling should be restricted to trained personnel in appropriately equipped facilities.
