Ion naming confusion with the "bi" prefix
I am little confused on when you use the "bi" prefix to denote the existence of a proton in front of an oxyanion.
For example, I know that [tex][HCO_{3}]^{-}[/tex] is called bicarbonate as well as hydrogen carbonate.
A problem arises when I try to define the various protonated versions of the phosphate and arsenate ions.
[tex]PO_{4}^{3-}[/tex] is phosphate...
[tex][HPO_{4}]^{2-}[/tex] is hydrogen phosphate if I am not wrong...
[tex][H_{2}PO_{4}]^{-}[/tex] is dihydrogen phosphate if I am not wrong...
But which of the above three would be referred to as the "biphosphate" ion??
I assume an analagous situation works for the arsenate ion? [tex]AsO_{4}^{3-}[/tex]
