Copper Turnings Extra Pure are thin, spiral-shaped shavings of elemental copper, produced from high-purity metal and widely used in laboratory applications requiring clean, reactive metal surfaces. Their large surface area makes them ideal for redox reactions, hydrogen generation experiments, and the preparation of copper salts through acid reactions. In educational and research settings, they are preferred for demonstrations involving displacement reactions and metal activity series studies. The extra pure grade guarantees minimal contamination, ensuring accurate and reproducible results. To prevent oxidation and maintain reactivity, copper turnings should be stored in dry, airtight containers.
Copper Turnings Extra Pure
Primary Uses
- Reactant in Inorganic Synthesis
- Used to prepare copper salts (e.g., copper nitrate, copper sulfate) by reacting with acids like nitric or sulfuric acid.
- Demonstrations of Redox Chemistry
- Ideal for showing metal displacement reactions, such as copper replacing less reactive metals from solutions (or being replaced by more reactive ones).
- Electrochemical Experiments
- Employed as electrodes in galvanic and electrolytic cells to demonstrate oxidation at the anode or reduction at the cathode.
- Metal Recovery Studies
- Used in precipitation reactions to recover other metals (e.g., silver or mercury) from their ionic solutions.
Secondary Uses
- Thermal Conductivity & Heat Transfer Experiments
- Because of its high thermal conductivity, it’s used to demonstrate metallic heat conduction.
- Teaching Tool in Reagent Purity or Metal Identification
- Helpful in qualitative tests for identifying pure metals or checking reaction completeness.
- Support for Organic Reaction Catalysis (when activated)
- Though less common than copper powder, cleaned or activated turnings may act as mild catalysts in some organic coupling reactions.
- Study of Metal Surface Reactions
- Used to study surface oxidation, passivation, or acid etching effects under controlled conditions.
