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.
Silica, which is present as H4SiO4 in all natural water, may depress the solubility of aluminum by forming co-polymer layer-type minerals, such as the clay minerals. Solid basic aluminum fluoride and other mixed species may be less soluble than simple hydroxides under some conditions.ilica, which is present as H4SiO4 in all natural water, may depress the solubility of aluminum by forming co-polymer layer-type minerals, such as the clay minerals.
