Chromic Acid Extra Pure – 500 gram Packs

Chromic Acid Extra Pure, commonly marketed in solid form as chromium trioxide, is an inorganic chromium(VI) compound with the molecular formula CrO3 and a molecular weight of approximately 99.99 g/mol. It is a powerful oxidizing agent used in selected oxidation reactions, specialized chemical synthesis, and advanced laboratory investigations involving redox chemistry. Chromium trioxide typically appears as dark red to reddish-brown crystalline flakes and reacts with water to form strongly acidic solutions containing chromium(VI) species. Its chemical reactivity makes it relevant to specific organic and inorganic chemistry procedures where a strong oxidant is required. The 500 gram pack is intended for laboratories with defined reagent requirements and appropriate chemical safety facilities. Chromium trioxide is highly hazardous, corrosive, carcinogenic, and capable of intensifying fires through its oxidizing action. Its use requires trained personnel, suitable exposure controls, compatible storage, and careful management of chromium-containing waste. The exact product identity should be confirmed before use.

Frequently Asked Questions About Chromic Acid

What is Chromic Acid Extra Pure commonly supplied as?

Solid products marketed as Chromic Acid Extra Pure commonly refer to chromium trioxide (CrO3), also called chromic acid anhydride. When dissolved in water, chromium trioxide produces an acidic solution containing chromium(VI) species. The solid compound and an aqueous chromic acid preparation are distinct product forms and should be identified accordingly.

What is the molecular formula and molecular weight of Chromic Acid supplied as chromium trioxide?

Chromium trioxide has the molecular formula CrO3 and a molecular weight of approximately 99.99 g/mol. Its empirical formula is also CrO3. These values apply to the solid chromium trioxide compound, not to an aqueous solution whose composition depends on concentration and chemical speciation.

What is the CAS number of chromium trioxide?

The CAS Registry Number for chromium trioxide is 1333-82-0. This identifier is associated with the solid compound also known as chromium(VI) oxide or chromic acid anhydride. Confirm the chemical name, formula, and identifier against the intended product before purchasing or using the reagent.

What is Chromic Acid used for in chemical laboratories?

Chromium trioxide is used as a strong oxidizing agent in selected organic synthesis procedures and specialized redox investigations. Because chromium(VI) compounds are carcinogenic and hazardous to health and the environment, applications require appropriate risk assessment, engineering controls, trained personnel, and compliant hazardous-waste management.

How should Chromic Acid be stored and handled safely?

Store chromium trioxide in a tightly closed, compatible container in a designated, dry storage area, segregated from combustible materials, organic substances, reducing agents, and other incompatible chemicals. Avoid dust exposure and contact with skin and eyes. Follow the current Safety Data Sheet and institutional procedures for handling and chromium-containing waste.

Storage Conditions for Chromic Acid

Store chromium trioxide in its original, tightly closed, chemically compatible container in a cool, dry, well-ventilated designated oxidizer storage area. Keep it segregated from combustible and organic materials, reducing agents, and incompatible substances. Prevent contamination, moisture exposure where specified, and unauthorized access. Follow the product-specific Safety Data Sheet and institutional requirements for hazardous chromium(VI) compounds.

Precautions for Handling Chromic Acid

Review the current Safety Data Sheet and institutional risk assessment before handling chromium trioxide. It is highly toxic, corrosive, carcinogenic, and a powerful oxidizer. Avoid dust exposure and direct contact, and use suitable protective equipment and properly designed engineering controls appropriate for chromium(VI). Keep it away from organic and combustible materials, avoid incompatible mixing, and ensure that spills and chromium-containing waste are managed by trained personnel under approved hazardous-material procedures.
