Also, SO4 2- can evidently not be acidic as it does not have a proton to donate. SO4 2- is a weak base because it is the conjugate base of the weak acid HSO4 -. H3PO4 is a weak acid, so it does not fully ionise in water. Hence, H2PO4- can be treated as a weak, base as it is the conjugate base of a weak acid.
