How can you tell if an aqueous compound acts as an acid or a base?
For example, if given NH2NH2, can’t this compound donate a H+ and also receive an H+?

Re: Acid or Base
Some compounds can either act as a base or an acid, those compounds are labeled as amphoteric. The best way would be to draw the lewis structure and see if it can actually give off a proton or if the Nitrogen has a lone pair. In some cases, although it is amphoteric, acting as a base/acid is more favorable resulting in the other one not usually happening. Hope this clarifies it.
