Solubility of ferrous iron and the solid-phase minerals that would be stable in a solution containing activities of 10 ppm of sulfate and 100 ppm of bicarbonate or related species is expressed by means of a stability-field&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;diagram&lt;/span&gt;&lt;span&gt;&amp;nbsp;with pH as abscissa and redox potential as ordinate.The&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;diagrams&lt;/span&gt;&lt;span&gt;&amp;nbsp;can be used to tell whether water injected in recharge wells may form precipitates that may plug the aquifer and have other uses in studies of natural water chemistry.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
