The pure water is neither base nor acid. This is because in pure water, ther is a small dissociation of water molecules giving the same amount of H+ and OH- ions. Therefore, ther is no excess of acid nor base ions. Reaction: H20 -> H+ + OH- The concentration of [H+]=[OH-]=10^-7 mol/dm3 You can read more here: http://ibchem.com/IB/ibnotes/full/aab_htm/18.3.htm

At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.
