Iron(III) phosphate, also ferric phosphate, [4] [5] is the inorganic compound with the formula Fe PO 4. Four polymorphs of anhydrous FePO 4 are known. Additionally two polymorphs of the dihydrate FePO 4 ·(H 2 O) 2 are known.
The iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
At pH 1 or lower, the phosphoric acid is practically undissociated. Around pH 4.7 (mid-way between the first two pK a values) the dihydrogen phosphate ion, [H 2 PO 4] −, is practically the only species present. Around pH 9.8 (mid-way between the second and third pK a values) the monohydrogen phosphate ion, [HPO 4] 2−, is the only species ...
Iron(II) phosphate, also ferrous phosphate, [3] Fe 3 (PO 4) 2, is an iron salt of phosphoric acid. Natural occurrences. The mineral vivianite is a naturally occurring ...
Thermolysis of iron(II) sulfate begins at about 680 °C (1,256 °F). 2 FeSO 4 Fe 2 O 3 + SO 2 + SO 3. Like other iron(II) salts, iron(II) sulfate is a reducing agent. For example, it reduces nitric acid to nitrogen monoxide and chlorine to chloride: 6 FeSO 4 + 3 H 2 SO 4 + 2 HNO 3 → 3 Fe 2 (SO 4) 3 + 4 H 2 O + 2 NO

The most notable difference between lithium iron phosphate and lead acid is the fact that the lithium battery capacity shows only a small dependence on the discharge rate. With very high discharge rates, for instance 0.8C, the capacity of the lead acid battery is only 60% of the rated capacity.
