In our Fe(III)-O-H model, we have included 3 solid phases: Fe2O3 (hematite), FeOOH, and Fe(OH)3. ... The 3rd one being an amorphous phase that can be metastable but kinetically observed in the solubility experiments.

Hydroxide salts of transition metals and Al3+ are insoluble. Thus, Fe(OH)3, Al(OH)3, Co(OH)2 are not soluble. Most sulfides of transition metals are highly insoluble, including CdS, FeS, ZnS, and Ag2S. Arsenic, antimony, bismuth, and lead sulfides are also insoluble.

FePO4 is a yellow brown solid at room temperature. It is insoluble in water. Its melting point is 250 ̊C (482 ̊F) and density is 3.056 g/cm3. ... The chemical name of FePO4 is iron(III). You may also call it ferric phosphate.

I- is much larger in size, so has higher tendency to lose electron, and hence is a good reducing agent. I- reduces Fe3+ to Fe2+ and itself gets oxidised to I2, hence FeI3 is unstable. ... So, it being an oxidising agent oxidises Fe2+ to Fe3+, which favours formation of FeCl3 and makes it stable.

The most commonly used iron-bearing minerals contain iron compounds as follows: hematite, Fe2O3 (70% Fe); magnetite, Fe3O4 (72.4% Fe) and of much less importance are: limonite, 2Fe2O3·3H2O (60% Fe); siderite, FeCO3 (48.3% Fe); pyrite, FeS2 (46.6% Fe) [1].

The bond character is polar covalent although the difference is very close to that of ionic bonds. So iron oxide is a polar covalent compound with ionic character.

Solubility of iron and iron compounds Elementary iron dissolves in water under normal conditions. Many iron compounds share this characteristic. Naturally occurring iron oxide, iron hydroxide, iron carbide and iron penta carbonyl are water insoluble.

What is the difference between FeO and Fe2O3? ... FeO is Iron(II) oxide and is made up of Fe2+ and O2- ions. Fe2O3 is Iron(III) oxide and it is made up of Fe3+ and O2- ions.

Therefore, iron(III) carbonate cannot exist in water. In solid state, most of iron(III) compounds are hygroscopic, which means that they have strong affinity for moisture. In aqueous environment, iron(III) is bound by water molecules and exists as [Fe(H2O)6]3+.

Well, anything above uranium is likely to be a solid too. There are only two liquid elements at room temperature and pressure; bromine and mercury. Few gases; noble gases, fluorine, chlorine, oxygen, nitrogen, and hydrogen. The rest are solids.
