A pure substance is by definition composed of one compound.

Is granite a pure chemical substance.

A pure substance can also be defined as a form of matter that has both definite. Oxygen for example is a pure chemical substance that is a colorless odorless gas at 25 c. But there are exceptions to this definition. A pure chemical substance is any matter that has a fixed chemical composition and characteristic properties.

It is considered a pure substance because it has a uniform and definite composition. Impure materials may be mixtures of elements mixtures of compounds. A pure substance or chemical substance is a material that has a constant composition is homogeneous and has consistent properties throughout the sample. To a non chemist a pure substance is anything composed of a single type of material.

Pure and impure chemical substances a pure element or compound contains only one substance with no other substances mixed in. A chemical substance may well be defined as any material with a definite chemical composition in an introductory general chemistry textbook. However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance.

A pure substance participates in a chemical reaction to form predictable products. A compound may be composed of different elements. Just like granite marble is a mixture. According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound.

All matter consists of various elements and chemical compounds but these are often intimately mixed together. Ordinary table salt is called sodium chloride. In chemistry a pure substance consists of only one type of atom molecule or compound. Mixtures contain more than one chemical substance and they do not have a fixed composition.

In other words it is free of contaminants. Common definition of a pure substance. All samples of sodium chloride are chemically identical. Just like granite marble is a mixture.
