pure
Definition
Pure means that something is made up of only one type of substance. For example, pure water is made up of only hydrogen and oxygen atoms.
Something that is pure does not have any impurities. Impurities are other substances that are mixed in with the main substance. For example, tap water is not pure because it contains impurities such as minerals and chemicals.
Pure substances are often used in scientific experiments because they are more reliable. For example, if you are doing an experiment to test the properties of water, you want to make sure that the water is pure so that the results of your experiment are accurate.
