PO3-3 is known as phosphite.
The compound PO3 is called phosphorus trioxide.
Some ions of phosphorous are: - phosphate, (PO4)3- - phosphite, (PO3)2- - phosphoros, (PO3)3- - hypophosphoros, (PO2)3-
Also phosphorous is the ion (PO3)3-.
Chromium (iii) Phosphite
PO2 is a polyatomic ion with the name hypophosphite. Its charge is -3. It has 2 less oxygen atoms than phosphate, the "parent" polyatomic, hence the -ite suffix and the hypo- prefix.
It is a chemical name for Beryllium Nitride.
Hg3PO4 is the chemical formula for mercurous phosphate.
-3 the whole formula for phosphite would look like: PO3^-3
Lithium has a charge of Li^+1, phosphite has a charge of PO3^-3. But overall, Li3PO3 would be neutral.
Rb3(PO3) is typically considered ionic in nature. Rubidium (Rb) is a metal and phosphate (PO3) is a polyatomic anion, leading to the formation of ionic bonds between the two elements.
copper(II) phosphate can be made by mixing an aqueous copper(II) solution (i.e. CuCl2 or CuBr2) with an aqueous phosphate solution (i.e. monobasic or dibasic phosphate). A fluffy, light blue precipitate forms immediately upon addition of the copper(II) solution to the phosphate solution.
+5In almost all compounds or ions containing both oxygen and another element, an oxygen atom has an oxidation number of -2. A phosphate ion is not an exception to this generalization. Therefore, the four oxygen atoms in PO4-3 have a total charge of -8, and the phosphorus atom must have a charge of +5 to result in an overall charge of -3 for the ion as a whole.
