How do I determine if a compound is amphoteric?

[Nika Kononov 3E]

A compound is amphoteric if it can act as an acid and a base. You can identify that a molecule is amphoteric if it can both accept and donate an electron.

[Albert 1I]

A compound is amphoteric if it can react as both a base and acid. For example, H2O is amphoteric because in a reaction with HCl it produces H3O+ ions (H2O + HCl --> H3O+ Cl-). In a reaction with NH3, H2O reacts to create OH- ions (H2O + NH3 --> OH- + NH4+).

A substance can be identified as amphoteric if it can act as both an acid and a base. To test this you can see if the compound can both accept and donate an electron with whatever it is reacting with. Water is amphoteric because it can donate or accept an electron depending on what it is reacting with.

[Naomi Christian 1E]

A compound is amphoteric if it can act as both an acid and a base. You can identify an amphoteric compound by seeing if it has a proton able to donate, and also if it can accept a proton.

A compound is amphoteric when it can act as both an acid and a base, so in different reactions, said compound will donate or accept protons.

[Crystal Ma 2J]

It can act as both an acid and a base, meaning that it should be able to either donate or accept protons.

[Akshat Katoch 2K]

A compound is amphoteric if it can act as an acid and a base. For #2 it talks about Bronsted. So if it acts like a Bronsted base and acid, then for the Bronsted acid you need an H+ so it can be donated, and for the base, you need a negative charge so you can accept an H+.

[Kurosh Zamiri 1I]

The definition of amphoteric is a substance that can act as both an acid and a base. Specifically, this means the substance can either donate or accept protons. A key example of this is water. Depending on the reaction, water can act as an acid or a base, defining it as amphoteric.

[Jessica Ghiuzelian 1H]

A compound is amphoteric when it can act as both an acid and a base, meaning that that compound can either accept or donate electrons.

[Jessica Li 1G]

Amphoteric substances can act as an acid or base.

[AJackman]

Draw the Lewis structure. If it can act as both an acid and a base, it is amphoteric.

[Genelle Marcelino-Searles 2G]

Amphoteric compounds can both donate and accept electrons, so it can act as both an acid and a base.

[Jason Ho 2L]

An amphoteric compound can either donate or accept a proton, which results in it acting as a base or acid. For example, water can donate a proton and become OH- or it can accept a proton and become H3O+.

[Brenda Tran 3C]

Amphoteric acts as both a base and acid. You can find this if the molecular name has a H in it to donate (base) and a negative charge to accept another electron (acid).

[Caitlyn Lo 2F]

Amphoteric compounds can either act as an acid or a base by either donating or accepting a proton.

[Gavin Trent 2F]

Amphoteric compounds are able to act both as an acid and as a base, depending on the conditions.

[Claire Kim 1F]

How do I determine if a compound is amphoteric?

If a compound is amphoteric is it's like the middle ground of bases and acids in the way that it could be both. You can determine this if the compound has the ability to donate and accept an electron.
