what is the charge of a PHOSPITE ?
and how do i write it?
phosphate = PO4-3
phosphite = PO3</-3
Here is a good site for all of the polyatomic ions, including phosphite ion.
(Broken Link Removed)
phosphite should be PO3-3
okay then, what is calcium phospite?
Ca3(PO3)3 in my book. However, to be fair about it, I looked on the web AND in The Merck Index and found CaHPO3 and it was labeled calcium phosphite. Technically, however, that should be called calcium hydrogen phosphite
