Answer 1

Step-by-step explanation:

A metaphosphate ion is an oxyanion that has the empirical formula PO−

3.[1] The structure of a metaphosphate ion can be described as being made up of PO4 structural units in which each unit shares two corners with another unit. This can come about in two ways.

A phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus atom is in the oxidation state +5, and is bonded to four oxygen atoms, one of them through a double bond, arranged as the corners of a tetrahedron. Two or more of these PO

4 tetrahedra may be connected by shared single-bonded oxygens, forming linear or branched chains, cycles, or more complex structures. The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H

n+2−2xP

nO

3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and (n+2)/2.

cyclic trimetaphosphate

Metaphosphates can be considered as salts of the corresponding metaphosphoric acids (HnPnO3n) although none of these acids has been isolated. The metaphosphoric acids can be formulated as H2O·P2O5. In comparison, phosphoric acid, H3PO4 can be formulated as 3H2O·P2O5 and pyrophosphoric acid, H4P2O7, as 2H2O·P2O5.

Metaphosphates can be used as an alternative of white phosphorus in organic syntheses.
