In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H3PO4. The phosphate or orthophosphate ion [PO4]3− is derived from phosphoric acid by the removal of three protons H+.

2023年8月29日 · Most other phosphates, such as FePO4 FePO 4, CrPO4 CrPO 4, BiPO4 BiPO 4, Ca3(PO4)2 Ca 3 (PO 4) 2, and Ag3PO4 Ag 3 PO 4 are only sparingly soluble. Phosphate …

Phosphorous acid (or phosphonic acid) is the compound described by the formula H 3 PO 3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.

PO 4 3- is a chemical derivative of phosphoric acid with a chemical name Phosphate. Phosphate is also called Phosphate ion or Orthophosphate . It is a trivalent inorganic anion and a conjugate base of hydrogen phosphate.

For the PO3 3- Lewis structure we first count the valence electrons for the PO3 3- molecule using the periodic table. Once we know how many valence electrons there are in PO3 3- we can distribute them around the central atom and attempt to fill the outer shells of each atom.

2023年3月13日 · Lewis structure of PO3- ion contains one double bond and two single bonds between the Phosphorous (P) atom and Oxygen (O) atoms. The Phosphorus atom (P) is at the center and it is surrounded by 3 Oxygen atoms (O). Let’s draw and understand this lewis dot structure step by step.

Phosphates have the formula PO 43- and a molar mass of 94.973 g/mol. An example of a phosphate is sodium phosphate. Three different types of phosphates are known. They are orthophosphate, PO 43-; metaphosphate, PO 32-; and pyrophosphate, P 2 O 73-. They have a combining power of 3.
