6A.11

Postby Ami_Pant_4G » Sat Nov 30, 2019 10:57 am

Write the chemical equations of the two proton transfer equilibria that demonstrate the amphiprotic character of (a) HCO3; (b) HPO42. Identify the conjugate acid–base pairs in each case.

Csn some one please explain how to do part b of this problem? Thanks in advance.

HPO4(2-) as an acid: PO4(3-) (conjugate base)
HPO4 (2-) as a base: H2PO4 (-1) (conjugate acid)...

I think the easiest way when you're told that the molecule is amphoteric is to just add a proton and minus a proton. So you would end up with PO4 (3-) and H2PO4 for HPO4.
