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.
Zinc oxide is a fine white powder that is insoluble in water. That simply means that if you dump a little zinc oxide into a cup of hot water and stir it around, youâll just end up with powder and water.Zinc oxide can occur naturally as the mineral zincite but most zinc oxide is synthetically produced.inc oxide is a fine white powder that is insoluble in water.
