Answer

$(i) : COOH^-$ $(ii) : {PO_4}^{3-}$

Work Step by Step

Write the equations where the $HCOOH$ and the ${HPO_4}^{2-}$ act like an acid: $(i) : HCOOH + H_2O --> COOH^- + H_3O^+$ $(ii) : {HPO_4}^{2-} + H_2O --> {PO_4}^{3-} + {H_3O}^+$ The bases formed in these reactions are the conjugated bases.
