==Typical inorganic chemical reactions==
==Analysis and characterization of  inorganic compounds==
The number of known chemical elements that occur naturally on [[Earth]] is 94 and the number of diverse inorganic chemical compounds derived by combinations of those elements is virtually innumerable. The characterization of those compounds includes the [[measurement]] of chemical and physical  properties such as [[boiling point]]s, [[melting point]]s, [[density (chemistry)|density]], [[solubility]], [[refractive index]] and the  [[pH]] and [[electrical conductivity]] of solutions.
The  techniques of qualitative and quantitative [[analytical chemistry]] can provide the composition of a chemical compound in terms of its constituent chemical elements and can thus determine the [[chemical formula]] of  a compound.
Modern laboratory equipment and techniques can provide many more details for characterizing chemical compounds. Some of the more commonly used modern techniques are:
* [[Chromatography]]: A process for separating mixtures into their component constituents.
* [[X-ray diffraction]] or [[X-ray crystallography]]: A technique that determines three-dimensional arrangement of atoms within a molecule.
* [[Spectrometry]] or qualitative [[Spectroscopy]]: A technique for the identification of substances through the [[electromagnetic spectrum]] emitted from or absorbed by them.
* [[Voltammetry]]: An [[Electrochemistryl|electrochemical]] method for studying a chemical substance by measuring the [[Voltage|electrical potential ]] and/or [[electric current]] in an [[electrochemical cell]] containing the substance.
