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.
The natural analogue of iron(II) hydroxide compound is a very rare mineral amakinite, (Fe,Mg)(OH) 2. Reactions. Under anaerobic conditions, the iron(II) hydroxide can be oxidized by the protons of water to form magnetite (iron(II,III) oxide) and molecular hydrogen. This process is described by the Schikorr reaction: 3 Fe(OH) 2 â Fe 3 O 4 + H 2 + 2 H 2 O. Anions such as selenite and selenate can be easily adsorbed on the positively charged surface of iron(II) hydroxide, where they are ...
