∙ 13y agochemically spoken, water is dihydrogenoxide, H2O. This is a single-component substance, and thus, "pure".
Naturally spoken, water never is pure. There is always a certain amount of salts and gasses dissolved in it, so it never reaches a 100% purity.Even if water is distilled & deionised it cannot be made "pure" in the sense of a single substance. It will ALWAYS be a mixture (99.99999% water, 0.00001% hydronium ions, 0.00001% hydroxide ions - figures approximately correct for 25 celcius - the % of water drops at higher temperatures with a corresponding increase in the latter two figures - research something called "Ionic Product of Water"). Water effectively "reacts with itself" and you can't stop it!!
