Water is a pure substance. This is because it has the same material all over and is made of one kind of substance throughout. Moreover, water cannot be separated into other materials. Water is a compound that contains two different elements: hydrogen and oxygen. When salt is added into water, it becomes a mixture.
Pure water, also known as purified water, is water from a source that has removed all impurities. Distilled water is the most common form of pure water. Pure water can be purified by carbon filtration, micro-porous filtration and ultraviolet oxidation. Some places use a combination of purification processes. The curiosity to learn about exciting concepts in science describes pure chemistry. Continue reading to explore what pure chemistry is and some examples involving pure chemistry research.
