Editing Phosphorus (section)

====Metal salts====
With metal [[cation]]s, phosphate forms a variety of salts. These solids are polymeric, featuring P-O-M linkages. When the metal cation has a charge of 2+ or 3+, the salts are generally insoluble, hence they exist as common minerals. Many phosphate salts are derived from hydrogen phosphate ({{chem2|HPO4(2-)}}).

Calcium phosphates in particular are widespread compounds with many applications. Among them, they are used to improve the characteristics of processed meat and [[cheese]], in [[baking powder]], and in toothpaste.{{r|Threlfall1951}} Two of the most relevant among them are [[monocalcium phosphate]], and [[dicalcium phosphate]].
