Actually saying the whole fact in terms of matter, will be a great way to grasp the concept superfastly. Elements and compounds are generally grouped under PURE SUBSTANCES. But, mixtures are grouped under IMPURE SUBSTANCES since mixture refers to a substance which has also other substance mix with it.

Now, pure substances are those substances which have a definite composition, bearing a fixed melting or boiling point, without mixing with any other substances. A pure substance always stays as a single substance.

For example, water, gold, oxygen, sugar, copper sulphate, calcium carbonate all are pure substances.

Conversely, an impure substance is a substance in which some other substances are also present in smaller quantities. The substance, which is present in another substance in smaller amount, is however termed as IMPURITY.

Elements, and compounds are always pure substances. Pure substances, however, can be made impure, by adding some impurities to them, i.e., by contaminating pure substances by impurities.

For example, if we add some amount of salt with a water, that water will become impure since we added some salt, and salt is the impurity here. Hence, in this case impure water refers to pure water + salt's impurity.

So, always remember in your mind that Pure Substance + Impurities = Impure Substance.

Now, we always want the pure substance, because it is undoubtedly the useful component in any impure sample. So, there are many ways for purification of any impure substance. When a substance will be treated with those chemical procedures, then the impurities present in it will disappear.
