How to tell if a salt is amphiprotic?
« on: June 17, 2019, 05:26:15 PM »
So I have a problem that deals with finding whether a solution is acidic or basic. Is there a way to tell is a species such as H2COO is amphiprotic? Thanks

Other than recognizing the identity of the compound and/or identifying its functional groups? I am afraid no.

I don't understand you question. What are you looking at? Some universal method to prove amphoteric behaviore?

H2COO is not amphiprotic. It is only an acid. It can donate a proton which makes it acid.

H2COO is HCOOH which in turn is H-C(=O)-O-H.  The H attached to O is acidic.  That is, it can come off the molecule as H+ leaving HCOO-.  HCOOH is called formic acid.
