What is a pure substance?

Answer

A pure substance is a single substance that is free from contamination. Ethanol and honey are examples of pure substances.

Water is a pure substance as long as it has not been contaminated. Hard water is not a pure substance because it has been contaminated by magnesium, calcium and other minerals.

Some educators define a pure substance as one that is made up of only one type of building block. Under this definition, elements and compounds are the only materials that would qualify as pure substances. Although compounds are made up of two or more elements, they are pure substances because their composition never changes.
