COPPER OXIDE (CUPRIC OXIDE) 

1. PRODUCT IDENTIFICATION

2. CHEMICAL STRUCTURE

2.1. Molecular Structure

Copper(II) oxide is one of the most stable oxide forms of copper. Each copper ion (Cu²⁺) is surrounded by four oxygen ions (O²⁻), exhibiting a monoclinic crystal structure. This structure is a tenorite-type structure where copper ions display square planar or square pyramidal coordination.

6. REACTIONS AND MECHANISM OF ACTION

6.1. Acid Dissolution Reactions

Copper oxide dissolves in mineral acids to form corresponding copper salts:

With Hydrochloric Acid:

CuO + 2HCl → CuCl₂ + H₂O

With Sulfuric Acid:

CuO + H₂SO₄ → CuSO₄ + H₂O

With Nitric Acid:

CuO + 2HNO₃ → Cu(NO₃)₂ + H₂O

6.2. Reduction Reactions

Copper oxide can be reduced to copper metal by reducing agents:

With Hydrogen:

CuO + H₂ → Cu + H₂O

With Carbon Monoxide:

CuO + CO → Cu + CO₂

With Carbon:

2CuO + C → 2Cu + CO₂

21. CRITICAL NOTICES AND BEST PRACTICES

CRITICAL NOTICES:

1. Heavy Metal Toxicity: Copper oxide is a heavy metal oxide. Ingestion, inhalation, or skin contact poses health risks. Should not be used in food or cosmetic applications due to toxicological effects.

2. Eye Contact: Causes serious eye damage (H318). Always wear safety goggles.

3. Environmental Hazard: Very toxic to aquatic life (H400/H410). Release to the environment must be strictly prevented.

4. Moisture Sensitivity: Hydration and caking may occur when exposed to moisture. Should be stored in dry conditions.

5. Reaction with Acids: Contact with acids may form toxic copper salts.

6. Reaction with Reducing Agents: May be reduced by contact with hydrogen, carbon monoxide, or carbon.

BEST PRACTICE RECOMMENDATIONS:

Storage:

• Store in dry, closed packaging; keep away from moisture

• Store separately from acids, ammonia, and reducing agents

• Keep tightly closed in original packaging

Handling:

• Use in well-ventilated areas

• Use dust mask (N95/FFP2), protective goggles, and gloves

• Avoid dust formation

• Wash hands after handling

Waste Management:

• Heavy metal oxide waste; dispose of at licensed disposal facilities

• Do not discharge into drains, sewers, or water bodies

• Consider recycling if possible

Emergency:

• In case of eye contact, rinse immediately with plenty of water and seek medical attention

• In case of dust inhalation, move to fresh air

• If large amount is swallowed, do not induce vomiting; seek immediate medical attention
