• For example, reacting copper granules with silver nitrate (AgNO3​) to demonstrate the displacement of silver by copper:
  Cu (s)+2AgNO3(aq)→Cu(NO3)2(aq)+2Ag (s)
• A classic high school or undergraduate chemistry experiment.

Copper can be used as a reductant in certain organic reactions, such as:

• Used in some organic synthesis or gas-phase reactions, especially in educational labs to show catalytic behavior.
• For example, copper catalyzes the decomposition of hydrogen peroxide or the Wurtz-type couplings.

Used with concentrated acids like sulfuric acid:

Cu+H2SO4→CuSO4+H2↑

• This reaction is slower than with zinc, but is used to compare the reactivity of metals.

The granules are used in:

• Galvanic cells (paired with another metal to produce current).
• Electrolysis experiments, especially when teaching basic electrochemical principles.

Labs might use granular copper to study:

• Surface reactions (e.g., oxidation, patination).
• Cleaning and passivation treatments.
• Microbial resistance or antimicrobial testing.

• Used in labs testing melting, sintering, alloying, or particle size behavior.
• May be mixed with binders for powder metallurgy experiments.

Deoxygenation of gas streams(e.g., removal of oxygen from nitrogen or argon).

• Heated copper granules can be used to scavenge oxygen in inert gas systems.

• High purity granular copper is available in small packs for laboratory use and in large pails for industrial applications.
• All sizes are Suitable for displacement reactions, catalysis, electrochemistry, and redox experiments.
