Why "meta" phosphoric acid always exit in a polymeric form?
Meta phosphoric
acids and their salts always
exist in dimeric, trimeric, tetrameric or in polymeric linear
as well as cyclic form, not in monomeric form due to the presence of weak (2p-3d- pi bond) bond the sodium
salts of trimer and hexamer is very famous salts.
How to pridict cyclic structure given compound/oxy-acid:
If
in given compounds number of
substituents are integral multiple of central atoms (except
P4O6,P4O10,P4S3,P4S10,(CH2)6N4,B4Cl4)
the compounds will be cyclic structure. And
number of central atoms must be three (3) or more than three.
For
example (1) ; H6P4O13 (4P+6OH+4O+3O(oxylinkage):
For
example (2) ; H3P3O9
(3P+3OH+3O+3O(oxylinkage):
For
example (3) ; H4P4O12 (4P+4OH+4O+4O(oxylinkage):
For
example (4) ; H6P6O18 (4P+6OH+6O+6O(oxylinkage):
Hexamer
of meta phosphoric acid exist as sodium salt which is called sodium metaphophate or sodium polymetaphosphate and
it is commercially known as "CALGON" and use as water softener.
