Can someone please give me an example of an amphoteric compound?

[Konmal Ali 1G]

Amphoteric compounds can act as both bases and acids. Examples of these include hydroxide, zinc oxide, and aluminum oxide. Another example of a compound includes beryllium hydroxide. I hope this helps!

An example of an amphoteric compound is bicarbonate ion: HCO3-. This molecule can both donate a proton (accept an electron) as it contains hydrogen, but it can also accept a proton (lose an electron) since it is an ion with a negative charge.

There are lots of examples but to list a few:
Aluminum chloride
Aluminum oxide
Lead oxide
Tin oxide
Copper oxide
Even amino acids! (E.g. glycine) this is due to the carboxyl group that gives off the amphoteric behavior
These amphoteric characteristics are shown by their ability to switch roles as bases/acids depending on the given reaction.

I have attached a diagram hopefully that helps! I'm more of a visual learner so this is what helped me the most

Hi, Amphoteric compounds are chemical substances which can react both as an acid and base. Some specific examples are hydrogen chloride, lead oxide, aluminum oxide, and a lot of metals (copper, zinc, tin, aluminum) can form amphoteric oxides or hydroxides. Hope this helps!

This visual is so helpful, thank you for sharing this Ivy!

Water! It can react as an acid and a base, so water is an example.

[Eric Sun 2G]

Amphoteric compounds can act as both bases and acids. This means that this compound as accept or donate electrons/protons depending on which definition of acids or bases you like to use. An example would be Ammonia, NH3. Ammonia can act as a bronsted lowry acid and donate a proton to become NH2-. Additionally, NH3 can act as a bronsted lowry base and accept a proton to become NH4+.

[Rachel Bartley 2B]

Amphoteric compounds have both acid and base properties. Metals such as zinc, beryllium, etc. can form amphoteric compounds. With this, some examples are zinc oxide and beryllium hydroxide.

[Anubhav_Chandla1G]

Examples of Amphoteric compounds - aluminum oxide and zinc oxide.

[Junyong Wu]

Such as BeO, Al2O3, Ga2O3, SnO2, Sb2O3, PbO2

[Elizabeth Kim 2K]

Hi! An amphoteric compound can behave as either an acid or a base, meaning it can either gain or lose a proton/Hydrogen atom in a reaction. A few examples of amphoteric compounds are water, bicarbonate, and hydrogen sulfate (bisulfate). Hope this helps!

[Cory Poon 3G]

I'm not sure if anyone has said it yet, but water is a really important amphoteric compound!

[almaortega]

if a compound has a negative charge AND H I believe it can be considered amphoteric. For example, in this weeks achieve, H2SO4 - (negative charge of 1) is amphoteric because it can donate AND accept protons.

[Jillian Sarquiz- 2B]

An example is water which can act as both a base and an acid.

For amphoteric compounds in class he went over a picture of what the amphoteric compounds. A good way to remember what elements these are is that it is the elements that are close to the zig zag pattern created from the metalloids on the periodic table.
