This value is specified as chemically neutral. However, chemically pure water has no buffer and hence reacts to the slightest contamination with a significant change in pH value. Therefore due to CO2 solution, a pH value of 4.5 and 5 is immediately set in previously chemically pure water with admission of air. &lt;ref name=&quot;Wiki&quot;&gt;Wikipedia&lt;/ref&gt;</div>
