What is the purest substance?
In chemistry, a substance is pure if it has a homogeneous chemical composition. At the nanoscale, this only applies to a substance made up of one type of atom, molecule, or compound. In the more general sense, a pure substance is any homogeneous mixture. Examples of pure substances include iron, steel, and water.
