In chemistry, a pure substance has a constant chemical composition. No matter where you sample a substance, it is the same. For chemistry homework, the safest examples of pure substances are elements and compounds. So, examples include gold, silver, helium, sodium chloride, and pure water. E...
In order to be a pure substance, the substance must contain only one type of element or compound. For example, gold only contains gold elements. If there is another substance present, then it is considered a mixture. The following are examples of pure substance: Water: Water is considered ...

A substance is a material that has a definite chemical composition and physical properties. It can be a pure element such as gold or copper, or a compound made up of multiple elements such as water (H2O) or table salt (NaCl).What are the types of substances?
Purity of a Substance: A chemical element is one that contains only atoms that are identical to each other in their atomic number, i.e., the number of protons. If they have atoms of other elements alongside it, then the substance is said to be impure. Mining op...
