Identifying Them?

Postby Frederick Keith_4C » Sun Dec 01, 2019 11:37 am

I understand that an amphoteric compound is one that can act as both an acid and a base, but I don't know how one can identify one. So my question is how do you identify an amphoteric compound??

You can identify an amphoteric compound by seeing if it would be able to both accept and donate hydrogen atoms.

On the periodic table, there is a diagonal band of amphoteric oxides closely matching the diagonal band of metalloids. You can also tell if it is able to accept and donate hydrogen ions. As for identifying them in a chemical equation, it's not necessarily important to know if it's amphoteric, just which characteristic its showcasing in that specific equation.

An amphoteric compound is one that can both accept and donate electrons when need be, so I would test the compound to see if that is the case. For example, H2O can accept an electron to become H3O+ or it can donate an electron to become OH- depending on the problem.
Additionally, amphoteric molecules contain elements that are metalloids.

A compound is identified as an amphoteric compound if it is able to donate or accept protons.

An amphoteric compound can both accept and donate protons/hydrogen atoms.

An amphoteric compound can be identified as both a acid and a base in different reactions.

So in this case, would water be amphoteric?

An amphoteric substance is one which can both donate hydrogen ions (protons) and also accept them.

Yes. Water is a prime example of an amphoteric compound. There are other important ones as well, though.

"In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid and as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. . . One type of amphoteric species are amphiprotic molecules, which can either donate or accept a proton (H+). Examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water." - Wikipedia excerpts
