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.
(sulphur dioxide + water â sulphurous acid). Alkaline [alkali: A base which is soluble in water.] solutions are made when soluble metal oxides or metal hydroxides dissolve in water. eg. Na 2 O(s) + H 2 O(l) â 2NaOH(aq). (sodium oxide + water â sodium hydroxide). Here are some acids and alkalis that you may recognise.Video: Acidic, alkaline or neutral.
