Why is the H2SO4 unable to accept a proton?
Correct answer: HS- NH3 Amphiprotic species are able to both accept and donate protons. According to the Brønsted-Lowry definitions of acids and bases, amphiprotic species can act as both acids and bases. H2SO4 will donate, but not accept a proton. PO will accept a proton, but has no proton to donate.
