âIt would have been impossible to grow up in the South from 1890 to World War I and not have heard or read [the lost cause version of history] many times over as the common sense of white Southern self-understanding.â
The iron(II) hydroxide reduces these ions to elemental selenium, which is insoluble in water and precipitates out. Note: pK sp = 15.097 where p is the-log and K sp is the Solubility Product Constant. This means it has a low tendency to dissolve, but is not entirely insoluble.ron(II) hydroxide. Iron(II) hydroxide or ferrous hydroxide is a compound with the formula Fe(OH) 2. It is produced when iron(II) ions, from a compound such as iron(II) sulfate, react with hydroxide ions. Iron(II) hydroxide itself is practically white, but even traces of oxygen impart a greenish tinge.
Contrast to popular belief, water is not the actual cause of rust. Pure water will not cause rust to form on the iron. It is contaminants and alien particles in the water that cause electrostatic charges (electrolytes), such as acid. For pH values below 4.0, iron oxide (FeO) is soluble. Thus, the oxide (oxygen) dissolves as it is formed instead of depositing on the metal's surface.
