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.
Iron (3 mg) was added as ferrous sulphate to 2 dl red wine, white wine and 7% alcohol and its absorption was then measured in 38 fasting male subjects.(The original concentrations of iron in the two wines were low, being 1.01-1.08 mg/l (red wine) and 0.13-0.20 (white wine].The geometric mean absorption from red wine was only 20% of that from the alcohol solution whilst more than 4 times as much was absorbed from white wine as from the alcohol.emoval of about 80% of the polyphenols in red wine increased the geometric mean iron absorption from 1.9% to 3.6%. In vitro experiments indicated that iron was less soluble and less dialysable in red wines than in white wines.
