6A. 11

Postby Doris Cho 1D » Sat Nov 30, 2019 6:51 pm

Write the chemical equations of the two proton transfer equilibria that demonstrate the amphiprotic character of (a) HCO 2; (b) HPO4^2- . Identify the conjugate acid–base pairs in each case.

can someone explain how I would start off by doing this?

Amphiprotic means the species can both accept or donate a proton. Draw two equations for each species, one where it accepts and the other where it donates a proton.

These compounds can act as both acids and bases. One reaction will produce H30+, while the other will produce OH-

For each (a) and (b), you would get two equations, one where the compound acts as a base and one where it acts as an acid.
