Question

Classify the following into homogeneous and heterogeneous matter:

Bronze which is an alloy of copper and tin

Answer 1

Bronze which is an alloy of Copper $\left(\mathrm{Cu}\right)$ and Tin $\left(\mathrm{Sn}\right)$ is a homogeneous matter.

• This is because, in Bronze, the particles (atoms) of Copper and Tin are distributed uniformly throughout and exhibit uniformity in properties.

Homogeneous matter: Any substance that exhibit uniformity in its composition and properties throughout its mass is known as a homogeneous matter. Homogeneous matter can be further divided into two parts i.e.;

• Pure substances: When only one type of constituent particles are present in the substance. Example: Substances like Copper $\left(\mathrm{Cu}\right)$, Iron $\left(\mathrm{Fe}\right)$ etc. and substances like Water $\left({\mathrm{H}}_2\mathrm{O}\right)$, Hydrochloric acid $\left(\mathrm{HCl}\right)$
• Homogeneous mixture: When more than one type of constituent particles are present in a substance. Example: A solution of salt and water, tea, etc.
