WebH3PO4, pKa1= 2.15, pKa2=7.20, pKa3=12.35 So it’s stronger because the pKa of H2SO4 is smaller than that of H3PO4. Of course this answer does not address ‘Why’. So, for this point consider the two Lewis dot structures above. You can see that sulfur has a formal 2+ charge while phosphorus is only 1+ .
