The anhydrous salt can be prepared by reaction of ferrous chloride with anhydrous hydrogen fluoride. [12] It is slightly soluble in water (with solubility product K sp = 2.36×10 −6 at 25 °C) [13] as well as dilute hydrofluoric acid, giving a pale green solution. [1]
Iron(II) carbonate, or ferrous carbonate, is a chemical compound with formula FeCO 3, that occurs naturally as the mineral siderite.At ordinary ambient temperatures, it is a green-brown ionic solid consisting of iron(II) cations Fe 2+
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known.
Iron (II) hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH) 2.It is produced when iron (II) salts, from a compound such as iron(II) sulfate, are treated with hydroxide ions.

It is possible to calculate the number of moles of Fe 2+ ions by using a colorimeter, because of the very intense color of Prussian blue. In physiology experiments potassium ferricyanide provides a means increasing a solution's redox potential (E°' ~ 436 mV at pH 7). As such, it can oxidize reduced cytochrome c (E°' ~ 247 mV at pH 7) in ...
