Exceptions: HSO4- and H2PO4-

Postby Sara Sadrolsadat 1G » Fri Dec 07, 2018 1:02 am

Why is it that HSO4- and H2PO4- act as acids unlike other anions? Is it more favorable somehow?

HSO4- and H2PO4- can act like acids because they have a free proton they are able to donate in a basic environment. Hope this helps!

Since both anions have an H, they can donate it to a base. This means it can be acidic. I also believe that H2PO4- can donate two protons, but i'm not quite sure

Is H2PO4- a polyprotic acid? What makes something polyprotic?

Something is polyprotic if it can donate more than one proton (Hydrogen)
