       Highly polar
       Constant motion

        Pure water contains small concentration of H  & OH as 
        well as H2O molec
       High energy collisions allows transfer of H+ ions from one 
        HO to another

   @ 25 C
     Equilibrium [H+] is 1x10-7 M
     Equilibrium [OH-] is 1x10-7 M
     Therefore the ion concentrations in pure water are equal 
      making it Neutral
