A pure substance is a substance that cannot be separated by physical means. eg. filtration, evaporation, distillation or chromatography. Examples of pure substances include water, gold, glucose, carbon dioxide, oxygen and hydrogen. A pure substance is made up of one type of particle. The particle that makes up water is H2O. The particle that makes up carbon dioxide is CO2. Each pure substance has its own set of unique set chemical and physical properties which helps identifies it. Water has a melting point of 0°C and a boling point of 100°C. It is also colorless and odorless. Gold however, is yellow in color, solid at room temperature and pressure and is is good conductor of electricity. read less

The term has a specific meaning in chemistry. A pure substance is a sample of matter with both definite and constant composition with distinct chemical properties. Ex. water diamond gold table salt (sodium chloride) ethanol brass bronze saline solution
