In nature, pure substances are generally homogeneous, with only one type of atoms or molecules. The majority of these compounds have a consistent or homogeneous makeup throughout. The boiling and melting points of the chemicals are fixed.
Tin, sulphur, diamond, water, pure sugar (sucrose), table salt (sodium chloride), and baking soda are examples of pure substances (sodium bicarbonate). In general, crystals are pure substances. Pure chemical elements such as tin, sulphur, and diamond are examples of pure things.
A pure substance is a single substance made up of only one sort of particle in chemistry. The temperature at which a substance melts and boils is affected by impurities.
A pure substance, such as water, air, or nitrogen, is one that has a constant chemical composition throughout. As long as the chemical composition of all phases is the same, a combination of two or more phases of a pure substance is still a pure substance.
It is impossible to break down an element into a simpler substance since it is a pure material made up of only one type of atom.
