Is Granite A Pure Chemical Substance

A pure substance or chemical substance is a material that has a constant composition is homogeneous and has consistent properties throughout the sample.

Is granite a pure chemical substance.

However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. Just like granite marble is a mixture. A pure substance participates in a chemical reaction to form predictable products. According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound.

A compound may be composed of different elements. Mixtures contain more than one chemical substance and they do not have a fixed composition. But there are exceptions to this definition. A pure chemical substance is any matter that has a fixed chemical composition and characteristic properties.

Just like granite marble is a mixture. It is considered a pure substance because it has a uniform and definite composition. A chemical substance may well be defined as any material with a definite chemical composition in an introductory general chemistry textbook. 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. However unlike granite marble is typically more than 90 calcium carbonate so it might count as a pure substance. In chemistry a pure substance consists of only one type of atom molecule or compound. Oxygen for example is a pure chemical substance that is a colorless odorless gas at 25 c.

Common definition of a pure substance. Impure materials may be mixtures of elements mixtures of compounds. So in addition to elements compounds and alloys a pure substance might include honey even though it consists of many different types of molecules. Very few samples of matter consist of pure substances.

A pure substance is by definition composed of one compound. All samples of sodium chloride are chemically identical. A pure substance can also be defined as a form of matter that has both definite. Ordinary table salt is called sodium chloride.
