Best ResponseYou've already chosen the best response.1Lets say, you have milk, alright? If you add cereal to it, it's no longer just milk. You're turning adding onto it. A pure substance is something that is only of one thing. Like..Say you have oxygen. Oxygen isn't a mixture of gasses, it's simply Oxygen. Nothing else but. That's a pure substance.
