We know that only non metal of P-block formed oxy acids except some metals. The
simple way to distinguish between ortho oxy acids and Meta oxy acid is that
after removal of a water molecule from a parental oxy acid, remain an oxy
acid obtained as product then parental oxy acid named with prefix "Ortho" and product named with a prefix
"Para". For Naming as ortho acid, that
acid should contain minimum three hydrogen atoms.
For Examples:
H3BO3 (√), H2CO3
(×), H4SiO4 (√), HNO3 (×), H3PO3 (√), H3PO4 (√), H2SO4 (×), HCl4 (×)
(×)
Ortho prefix will not used.
(√)
Ortho prefix will used.
Meta acids and their salts always
exist in dimeric, trimeric, tetrameric or in polymeric
form, not in monomeric form.
[The tendency of polymerisation is observed as SiO4 4- > PO4 3- > SO4 2- > ClO4 -]
