Your Ad Here	Ore dressing a method for concentrating the important part of the ore from the original mineral by physical means. Organometallic compounds the term organometallic is usually restricted to those compounds in which a metal atom (including non-metallic elements like boron, silicon, phosphorus, arsenic etc., which are less electronegative than carbon) is bonded directly to a carbon atom of atleast one organic group radical of molecule). Organometallic compounds would include various hydrocarbon derivatives, carbonyls, carbides, certain chelate complexes, but do not include carbonates of metals complexes of the metals with organic amines and metallic salts of organic acids.
Orgel diagrams simple graphs showing the relation between the energies of various electronic states and their crystal field splitting. Orpiment refers to a natural yellow mineral form of arsenic (III) sulphide, As2S3. The name has been also used for the synthetic compound, which finds use as a pigment. Orthoboric acid, H₂BO₃ it is used as a preservative for milk and food stuffs, for washing eyes, manufacture of enamels and heat and shock resisting glasses.
Ortho-nitrotoluence NO₂C₆H₄CH₃, a yellow liquid boiling at 220.4˚C; insoluble in water; used to produce toluidine and dyes. Also known as ortbo-methylnitrobenzene. Orthophosphate one of the possible salts of orthophosphoric acid; the general formula in M₃PO₄, where M may be potassium as in potassium orthophosphate, K₃PO₄ Orthophosphoric acid H2PO4 a white solid that can be made by reacting phosphorus (V) oxide with water or by heating yellow phosphorus with nitric acid. An aqueous solution it has a sharp taste and has been used in the manufacture of soft drinks.	Your Ad Here
Orthophosphorus acid H2PO3 a colourless deliquescent solid that can be prepared by the action of water on phosphorus (III) oxide or phosphorus (III) chloride. It is a dibasic acid producing the anions H₂PO₃ and HPO₃ in water. The acid and its salts are slow reducing agents. Osmate a salt or ester of osmic acid, containing the osmate radical, OsO4 -; for example, potassium osmate (K₂OsO₄). Osmic acid the name given to osmium tetroxide and its solution in water. This solution contains free OsO4. In alkaline solution [OsO₄(OH₂)]² ions are present.

Also known as osmium oxide; osmium tetroxide. Osmium tetroxide OsO₄ an oxide of osmium used in electron microscopy to stain and fix biological material, especially animal tissues. Osmium, Os at.no. 76, at.wt. 190.2, m.p. 3045˚C, b.p. 5027˚C, d 22.6. Osmium is a platinum group metal. It occurs as a sulphide or as osmiridium. The metal is hep and has very similar properties to Ru. Oxygen at high temperatures gives OsO₄. Os is used for hardening purposes in alloys with other plantinum metals
