Is Granite A Pure Chemical Substance

Ordinary table salt is called sodium chloride.

Is granite a pure chemical substance.

In chemistry a pure substance consists of only one type of atom molecule or compound. A compound may be composed of different elements. Just like granite marble is a mixture. So in addition to elements compounds and alloys a pure substance might include honey even though it consists of many different types of molecules.

But there are exceptions to this definition. Very few samples of matter consist of pure substances. In other words it is free of contaminants. Just like granite marble is a mixture.

Oxygen for example is a pure chemical substance that is a colorless odorless gas at 25 c. A pure chemical substance is any matter that has a fixed chemical composition and characteristic properties. 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.

It is considered a pure substance because it has a uniform and definite composition. However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. All matter consists of various elements and chemical compounds but these are often intimately mixed together. All samples of sodium chloride are chemically identical.

To a non chemist a pure substance is anything composed of a single type of material. A pure substance or chemical substance is a material that has a constant composition is homogeneous and has consistent properties throughout the sample. Impure materials may be mixtures of elements mixtures of compounds. 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. A pure substance is by definition composed of one compound. Common definition of a pure substance. A pure substance participates in a chemical reaction to form predictable products.
