10.0pt;font-family:Arial;color:navy'>Distilled water is classically produced by
heating water to evaporation and subsequent condensing on a cold surface. In
the process most impurities are either evaporated off ahead of the water (in
the case of most organics), or left behind (in the case of minerals). The water
is also effectively <span class=SpellE>deionized</span> because the salts are
left behind. It is fairly pure water. To get very pure water it needs to be re-distilled
several times.<o:p></o:p></span></font></p>
