  Inorganic compound - Wikipedia, the free encyclopedia
Although the number of inorganic compounds is huge, it is indeed overshadowed by the number of organic compoundscompounds which contain carbon and hydrogen bonded to each other, which comprise the vast majority of all compounds known.
At the same time, many inorganic compounds exist in organisms, and are essential to life: sodium chloride (common salt), carbonic acid, phosphate ions and many more.
Carbon compounds are sometimes erroneously considered to be all organic; many compounds that contain carbon, however, are defined as strictly inorganic: carbon monoxide, carbon dioxide, carbonates, to name but a few.

 IUPAC nomenclature of inorganic chemistry - Wikipedia, the free encyclopedia
Ideally, every inorganic compound should have a name from which an unambiguous formula can be determined.
Compounds with a positive ion (cation), the name of the compound is simply the cation's name (usually the same as the element's), followed by the anion.
Hydrates are ionic compounds that have absorbed water.

 Supported arene complex olefin catalysis - Patent 4299936
It is preferred that the surface area of the inorganic compound is at least 1 m.sup.2 /g and it is particularly preferred that the area is at least 10 m.sup.2 /g and especially 30 m.sup.2 /g.
Suitable inorganic compounds include alumina, mixtures of alumina and silica, the mixed oxide of aluminum and silicon, magnesium dihalide and manganese dihalide, and, in the case of the latter two compounds, in order to achieve a high surface area it is desirable that they be subjected to a grinding operation.
However, the inorganic compound may be subjected to a grinding step either before or after it has been contacted with the transition metal compound, and it is not necessary to effect grinding of the inorganic compound in the presence of the transition metal compound.

 Re: what is the difference detween an inorganic and organic compound?
Inorganic compounds are produced by non-living natural processes or by human intervention in the laboratory.
An organic compound is whatever an organic chemist says it is; an inorganic compound is whatever an inorganic chemist says it is.
Normally organic chemists study organic or organometallic compounds, and inorganic chemists study organometallic compounds or inorganic compounds.

 Class Definition for Class 423 - CHEMISTRY OF INORGANIC COMPOUNDS
Processes of preparation of an inorganic compound or a nonmetallic element which include chemical treatment or preparation are classified in the appropriate compound or element subclass, unless a process subclass is specifically provided therefor under the compound or element subclass, even though combined with a purely physical operation precedent, subsequent, or both.
When a process produces an inorganic compound for Class 423 and a hydrocarbon compound for Class 585, both of which are intended to be recovered, the patent is classified as an original in Class 423 and cross-referenced to Class 585.
Processes wherein a mixture is chemically treated to obtain or recover a compound of a metal contained in the original mixture as an element, a compound or a precursor transmutable to the metal.

 Inorganic Oxidizing Agents   (Site not responding. Last check: 2007-10-08)
Inorganic oxidizing agents can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers).
Some inorganic oxidizing agents are salts of metals that are soluble in water; dissolution dilutes but does not nullify the oxidizing power of such materials.
Compounds that inherently contain a group that is a reducing agent and an oxidizing agent are classed in both Group 44 (Inorganic Oxidizing Agents) and in Group 45 (Inorganic Reducing Agents; for example, ammonium nitrate).

 Chemical Sciences: Stoichiometry: Principles of Chemical Nomenclature
Organic chemistry is the study of the covalent compounds based on the elements carbon and hydrogen.
Because organic chemistry is the study of carbon-hydrogen compounds, organic compounds are named by giving the chain or other structure of the carbon-hydrogen atoms and substituting into that structure the names of any other elements or groups of elements and the particular places at which they are present.
Inorganic compounds, however, are still named according to the principle that the name of an inorganic compound is derived from the names of the chemical elements which make up that compound.
