Question

Answer 1

Answer #1

a)

H2SO4 can only donate proton.

b)

H3PO4 can only donate proton

c)

H3AsO4 can only donate proton.

d)

HPO42- can donate proton and form PO43-

HPO42- can accept proton and form H2PO4-

This is amphiprotic.

e)

My professor explained that Not all polyprotic acids are amphiprotic because for instance, the second H of H2SO4 doesn’t come off strongly like the first H. However, this explanation doesn’t explain the reason why H2SO4 is not amphiprotic to me. To me, H2SO4 cannot accept a H+, but can donate a H, which is the reason why it’s not an amphiprotic. In contrast, H2PO4- is amphiprotic because it can accept a H+ to become H3PO4 and also donate a H...
