  <dc:description>&lt;p&gt;The association constant for the dissolved species MnHCO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;+&lt;/sup&gt; was experimentally determined to be 63. From this value and a published constant for the species MNSO&lt;sub&gt;4&lt;/sub&gt; aq., a diagram was prepared showing per cent of dissolved manganese complexed in the presence of 10 to 10,000 p.p.m. bicarbonate and 1.0 to 10,000 p.p.m. sulfate. The rate of oxidation of Mn&lt;sup&gt;+2&lt;/sup&gt; in aerated water is greatly increased by increasing pH, and is retarded when SO4&lt;sup&gt;-2 &lt;/sup&gt;and HCO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt; are present.&lt;/p&gt;</dc:description>
