![]() ![]() The Fe 2 S 3 like pyrite shows some conductivity in semiconductors with some resistivity of 1ohm m -1.Fe 2 S 3 is a polar compound as the bond between the atoms is ionic, indicating that electrons are responsible for making the bonds.The structure of Fe 2 S 3 is trigonal layered as the atoms of the chemical are linked with each other by making different layers of trigonal shape and the distance of each particle is 2.5967 A°. Its molecular weight is 226.9 g/mol.The reactivity of iron hydrogen sulfide is always high in liquid medium. Ferric Sulfide hydratesįe 2 S 3 forms hydrates (Fe 2 H 3 OS 3 ), the IUPAC name is Iron Hydrogen Sulfide. Let us discuss whether Fe 2S 3 is paramagnetic or not.įe 2 S 3 is paramagnetic in nature as the color is black which is due to the phenomena of unpaired electron. Paramagnetism is a phenomenon where the electrons are not paired at the last orbital of an atom. Is Ferric Sulfide odourlessįe 2 S 3 is an odourless compound. Ferric Sulfide acidity/alkalineįe 2 S 3 does not contain acidity or alkaline form as there is a lack of atoms, hydrogen which are responsible for the acidic nature of any chemical compound. The oxidation state of Ferric is 3 + and the oxidation state of Sulfide is 2 –, as the atoms of both chemicals combine the oxidation state atoms will merge in opposite to each other and thus the formula is Fe 2S 3. The electronic configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 and S 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6. Let us explain the electronic configuration of Fe 2S 3. The electronic configuration is the division of electrons around the orbitals in the atoms they are named s,p,d, and f. The ionic radius of Fe 2 S 3 is 123.5 pm (pico-meter). Ionic bond in Fe 3S 3 Ferric Sulfide ionic/covalent radius Ferric Sulfide ionic/covalent bondįe 2S 3 is bounded by ionic bonds as the oxidation states of both Sulfide and iron are different from each other and to satisfy the valency and create a bond, exchanging of electrons takes place due to which both of them attend charge and become ions, and forms the ionic bond. ![]() Ferric Sulfide state at room temperatureįe 2 S 3 is solid at room temperature as it is the mineral compound of the sulfur family, but due to the solid nature of iron and strong intermolecular forces between the atoms, it needs a high temperature to change the state which cannot be possible at room temperature. The boiling point of Fe 2 S 3 is 760 mm Hg, this is high because of the strong bonds between the atoms of Fe 2 S 3, thus a big amount of energy is required break the bonds so that the compound can get boiled at a certain temperature. The melting point of Ferric Sulfide is 1,194 ☌, this is high due to the intermolecular space as Fe 2S 3 is a solid compound in which molecules or atoms are compacted very closely and it needs a high temperature at which it starts to melt. Ferric Sulfide molar densityĤ.84 g/cm 3 is the molar density of Fe 2 S 3. The viscosity of Fe 2 S 3 is 4.6 Pa/s at 260.15 K and 0.0070 Pa/s at 285.15 K, both the values are very high due to the solid nature and insolubility of the Fe 2 S 3 with inorganic solvents. Ferric Sulfide colorįe 2 S 3 is black in color and is insoluble in water. The molar mass of Fe 2S 3 is 87.910 g/mol.
