Is copper a pure substance, a homogeneous mixture, or a heterogeneous mixture? Explain.

Question:- Is copper a pure substance, a homogeneous mixture, or a heterogeneous mixture? Explain.

Answer: Pure substance

Copper can be rightly said to be a pure substance; it is a metal. Still, it is a chemical element that has a symbol, Cu, and its atomic number is 29. From the formulation point of view, copper is homogeneous since all the components in it are Copper atoms alone. It is noteworthy that these structures are also comparatively uniform, so the material as copper will exhibit shared properties regardless of whether one is studying a small chunk or a rod of copper. In the form of wire, sheet or chunk, pure copper does not change in either its chemical or physical characteristics. It is however significant to point out that although the copper that is initially mined may be contaminated with other elements, chemically pure copper is still a pure compound. This is basic chemistry and material science where it is possible to talk of separate substances such as copper and mixtures which are two or more substances in variable ratios.
