HCO3- and H2SO3

Postby Ariel Lucas 1H » Sat Dec 09, 2023 5:59 pm

Hi! I am wondering why H2SO3 is not amphoteric and why HCO3- is amphoteric, and also exactly how to tell. Is it necessary to draw out the Lewis structure to see whether the structure is stable if you add or take away an H+? Thank you!

thats because H2SO3 cannot act like a base and acid like HCO3. Hope that helps.

The second one is amphoteric because it acts like both an acid and a base while the first one doesn’t
