Give two examples of pure substances
A pure substance is any single type of material that are made of only one type of atom or only one type of molecule. Also, a pure substance can be defined as any single type of material that has not been contaminated by another substance.
Examples of Pure Substances: 1. Gold
It has the same composition no matter where it comes from. Gold is made up of gold atoms. There are no other elements or compounds added to gold.
2. Diamonds
They are formed deep within Earth in only a very few areas. All the particles in a diamond are the same.
3. Water
Considered a pure substance if the water contains only hydrogen and oxygen. Pure water is difficult to find in nature. Even the clearest spring water contains dissolved minerals. In nature, pure substances tend to mix with other substances
4. Baking soda
Although there are a multitude of uses for baking soda, in its simplest form, it is not contaminated with any other chemical compounds.
5. Table salt
One of the most common household chemicals. Table salt is 97% to 99% sodium chloride. Pure sodium chloride is an ionic crystal solid.
