This reaction is not so straightforward.....

Explanation:

It is a fact that should we mix a heavy metal salt, with phosphoric acid, what we get out is the biphosphate....

i.e. #H_3PO_4(aq) + Ba(OH)_2(s) rarr Ba{HPO_4}(s)darr + 2H_2O(l)#

And so this not a simple acid-base reaction....

Anyway, you will have to reconcile this fact with what is taught in your lesson.
