What would the pH at the half-equivalence point be for the first ionization of the triprotic acid phosphoric acid (H3PO4)

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
