If a solution of hypobroumous acid is added to a solution of sodium phosphate, a reaction takes place to a large extent to produce hydrogen phosphate ion and the hypobromite ion. Which base is weaker, the phosphate ion or the hypobromite ion?
My equation I came up with is:
HOBr(aq) + Na
3PO
4 (aq)

HPO
42- + OBr
-I concluded that:
HOBr(aq) - stronger acid
Na
3PO
4 - stronger base
HPO
42- - conjugate acid (weaker acid)
OBr
- - conjugate base (weaker base)
Am I correct in thinking that OBr
- is the weaker base? My logic is that in a large extent reaction the reaction goes from stronger to weaker. Also, the stronger the acid, the weaker its conjugate base. Does this make sense?
