Phosphates
Inorganic salts of phosphoric acid.
Year introduced: /blood was BLOOD PHOSPHATES 1963-1967
Phosphorus Acids
Inorganic acids that contain phosphorus as an integral part of the molecule.
Year introduced: 1994
Phosphorus Compounds
Inorganic compounds that contain phosphorus as an integral part of the molecule.
Year introduced: 1998
Phosphoric Acids
Inorganic derivatives of phosphoric acid (H3PO4). Note that organic derivatives of phosphoric acids are listed under ORGANOPHOSPHATES.
Year introduced: 1968
Ions
An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.
Inorganic Chemicals
A broad class of substances encompassing all those that do not include carbon and its derivatives as their principal elements. However, carbides, carbonates, cyanides, cyanates, and carbon disulfide are included in this class.
Electrolytes
Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant and Hackh's Chemical Dictionary, 5th ed)
Anions
Negatively charged atoms, radicals or groups of atoms which travel to the anode or positive pole during electrolysis.
Year introduced: 1974
Acids, Noncarboxylic
Inorganic acids with a non metal, other than carbon, attached to hydrogen, or an acid radical containing no carbon.
Acids
Chemical compounds which yield hydrogen ions or protons when dissolved in water, whose hydrogen can be replaced by metals or basic radicals, or which react with bases to form salts and water (neutralization). An extension of the term includes substances dissolved in media other than water. (Grant and Hackh's Chemical Dictionary, 5th ed)
