Copper Oxide Black – 500 gram Packs

Copper Oxide Black, also known as Copper(II) Oxide or Cupric Oxide, is an inorganic compound with the chemical formula CuO. It contains copper in the +2 oxidation state and occurs as a black solid with a molecular weight of approximately 79.55 g/mol. Copper(II) Oxide is insoluble in water under ordinary conditions and reacts with suitable acids to form copper salts and water. Its chemical properties make it relevant to inorganic chemistry, analytical experiments, thermal decomposition studies, and the preparation of copper-containing materials. Copper Oxide Black Laboratory Reagent is intended for suitable educational, university, and research laboratory procedures when its specifications meet the requirements of the selected method. It is also used in investigations involving metal oxides and chemical reduction reactions. Appropriate dust control, personal protective equipment, and responsible waste management are essential because copper oxide dust can be harmful and the compound is hazardous to aquatic environments.

Frequently Asked Questions About Copper Oxide Black

What is Copper Oxide Black used for in laboratories?

Copper Oxide Black is used in inorganic chemistry experiments, acid–base reaction studies, controlled reduction investigations, and selected materials research procedures. It is relevant to the study of metal oxides and copper chemistry. Its suitability depends on the experimental method, required specifications, and applicable safety controls.

What are the chemical formula and molecular weight of Copper Oxide Black?

Copper(II) Oxide has the chemical formula CuO and a molecular weight of approximately 79.55 g/mol. Its empirical formula is also CuO because the copper-to-oxygen atom ratio is already expressed in its simplest whole-number form.

What is the CAS number of Copper Oxide Black?

The CAS Registry Number for Copper(II) Oxide is 1317-38-0. This identifier distinguishes CuO from Copper(I) Oxide, which has the formula Cu₂O and a different CAS number. Confirming the chemical identity is important for purchasing, inventory management, and selecting appropriate laboratory procedures.

Does Copper Oxide Black dissolve in water?

Copper(II) Oxide is insoluble in water under ordinary conditions. However, it reacts with suitable acids to form copper salts and water. Its limited water solubility makes it useful in selected heterogeneous reaction experiments, provided the chosen reagents and procedures are compatible with the material.

How should Copper Oxide Black be stored and handled safely?

Store Copper Oxide Black in a tightly closed, compatible, clearly labelled container in a cool, dry location. Avoid generating or inhaling dust, wear suitable protective equipment, and prevent release into drains or the environment. Follow the current Safety Data Sheet for specific storage, spill response, and hazardous waste disposal requirements.

Storage Conditions for Copper Oxide Black

Store Copper Oxide Black in a tightly closed, compatible, clearly labelled container in a cool, dry, well-ventilated location. Protect the material from contamination and minimise dust formation during storage and transfer. Keep it away from incompatible substances and prevent accidental release into drains or the environment. Follow the current Safety Data Sheet and institutional chemical storage procedures.

Precautions for Handling Copper Oxide Black

Review the current Safety Data Sheet before handling Copper Oxide Black. Wear suitable chemical-resistant gloves, protective clothing, and safety goggles, and avoid inhaling dust or allowing the material to contact skin and eyes. Use appropriate ventilation during weighing and transfer. Prevent environmental release and follow institutional procedures for spill management and hazardous waste disposal. Conduct heating or reduction experiments only with appropriate equipment and supervision.
