Pure substances are composed of a single element or compounds. Combinations of different substances are called mixtures. Homogeneous mixtures are mixtures of two or more compounds (or elements) that are not visually distinguishable from each other.
A pure substance is a single kind of matter that cannot be separated into other kinds of matter by any physical means. A pure substance always has a definite and constant composition. A mixture is a physical combination of two or more pure substances in which each substance retains its own chemical identity.
Pure substances offer uniformity and fixed compositions, while mixtures provide diversity and flexibility. Both concepts play pivotal roles in the intricate tapestry of matter, influencing everything from the air we breathe to the materials that construct our world.
When we speak of a pure substance, we are speaking of something that contains only one kind of matter. This can either be one single element or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties.
Pure substances can be elements made up exclusively of one kind of atom, or they can be compounds made up of molecules that include two or more elements. Mixtures can be homogeneous or heterogeneous depending on how finely mixed the components are.
Mixture and pure substance are two different types of matter. A mixture is a combination of two or more substances that are physically combined and can be separated by physical means. It does not have a fixed composition and can vary in its properties depending on the ratio of its components.

The main difference between pure substance and mixture lies in their composition. A pure substance contains only one kind of compound. It can be the same molecule or atom. Mixtures are composed of several kinds of compounds. However, it’s important to look at them individually in order to understand the nature of these substances better.
A sample of matter is one of two things – it is either a pure substance (that is, a single substance) or it is a mixture of two or more substances. A pure substance contains only one type of substance.
You can classify matter as a pure substance, or as a mixture. Learn the differences between the two and the different types of each.
