Phosphate Formula - Chemical Formula of Phosphate Formula .

Phosphate formula, also known as Phosphate ion formula or Orthophosphate formula, is given in this article. This salt of phosphoric acid has one central phosphorus atom which is surrounded by four oxygen atoms in a tetrahedral shape. A phosphate salt is obtained when a positively charged ion gets attached to the oxygen atoms that are negatively charged and forms an ionic compound.

Phosphate rock is also the source of by-product fluorine. Apatite & Rock Phosphate containing 3 to 4% CaF 2 are useful for recovery of fluorite. Hydrofluoro-silicic acid is recovered as by-product from phosphoric acid plants during processing of rock phosphate. Phosphate rocks are also considered as a significant and secondary resource of uranium.
