An organic base is an organic compound which acts as a base. Organic bases are usually, but not always, proton acceptors. They usually contain nitrogen atoms, which can easily be protonated. For example, amines or nitrogen-containing heterocyclic compounds have a lone pair of electrons on the nitrogen atom and can thus act as proton acceptors ...
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species . Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety .
Organic minerals are minerals that contain carbon, with some exceptions for historical reasons. Subcategories. This category has only the following subcategory. O.
Mindat.org uses to give the chemical formula of some minerals as a range (between parentheses, if tin dominant then herzenbergite: (Sn,Pb)SnS 2; otherwise teallite: (Pb,Sn)SnS 2), on the other side the IMA Database of Mineral Properties/ Rruff Project uses to give the ideal chemical formula of the solid solution end member (herzenbergite: SnS).
An organic compound is any compound containing carbon, aside from some simple ones discovered before 1828. There are three classes of organic mineral: hydrocarbons (containing just hydrogen and carbon), salts of organic acids, and miscellaneous. Organic minerals are rare, and tend to have specialized settings such as fossilized cacti and bat ...
