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.

Common definition of a pure substance. Pure and impure chemical substances a pure element or compound contains only one substance with no other substances mixed in. All matter consists of various elements and chemical compounds but these are often intimately mixed together. So option b sodium chloride is a right option.

However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. All samples of sodium chloride are chemically identical. To a non chemist a pure substance is anything composed of a single type of material. Mixtures contain more than one chemical substance and they do not have a fixed composition.

According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound. A pure substance can also be defined as a form of matter that has both definite. In other words it is free of contaminants. A pure substance participates in a chemical reaction to form predictable products.

A compound may be composed of different elements. Very few samples of matter consist of pure substances. But there are exceptions to this definition. Impure materials may be mixtures of elements mixtures of compounds.

Oxygen for example is a pure chemical substance that is a colorless odorless gas at 25 c.
