Cupric Carbonate Extra Pure

Whatsapp Order

Cupric Carbonate Extra Pure is a fine, green, high-purity compound used in laboratories for inorganic synthesis, analytical chemistry, and educational demonstrations. It serves as a reliable source of copper ions in reactions and decomposes upon heating to form copper oxide, making it useful for studying thermal decomposition. In qualitative analysis, it is employed to observe characteristic reactions of copper salts. Its extra pure grade ensures minimal interference from impurities, supporting accurate experimental outcomes. Cupric carbonate should be handled in a dry environment and stored in tightly sealed containers to prevent degradation and maintain stability.

Cupric Carbonate Extra Pure

Primary Uses

Precursor for Copper Compounds
- Commonly used to prepare other copper(II) salts (like CuCl₂, Cu(NO₃)₂) via reaction with various acids.
- Ideal for inorganic synthesis training.
Qualitative Inorganic Analysis
- Helps students observe typical copper ion reactions—green-blue color is visually distinctive.
- Demonstrates decomposition and acid reactions in teaching labs.
Catalyst Precursor or Component
- Converted to CuO (cupric oxide) by heating, which is then used as a catalyst in redox and organic reactions.
Pigment Preparation Studies
- Historically used in pigments (verdigris) and now studied in labs exploring historical art materials.

Secondary Uses

Thermal Decomposition Experiments
- Upon heating, it decomposes to CuO and CO₂, making it useful for thermal stability demonstrations and stoichiometry exercises.
CO₂ Absorption and Gas Evolution Studies
- Reacts with acids to release carbon dioxide gas, ideal for gas collection experiments.
Nanomaterial Synthesis
- Acts as a precursor in nano copper oxide or copper carbonate material synthesis, especially in materials science labs.
Demonstration of Metal Carbonate Behavior
- Used to show characteristic properties of transition metal carbonates vs alkali/alkaline earth counterparts.
