Examples of amphoteric compounds

Postby Marni Kahn 1A » Thu Nov 28, 2019 6:44 pm

Are we responsible for memorizing the amphoteric compounds shown to us in class, or should we just understand their importance?

I'd say that it wouldn't hurt to memorize them because they follow along a pattern in the periodic table. It's a slightly skewed diagonal line of elements. Since Dr. Lavelle showed us exactly which ones are in class, then there's a chance that we might have to recall them in some manner for the final.

If I recall correctly, Lavelle said we would need to be able to identify the amphoteric compounds he showed us in class

i think Lavelle said to memorize the diagonal line of elements on the periodic table.

The diagonal band they are referring to includes Be, Al, Ga, Sn, Sb, and Pb. The examples Lavelle used in class were all bonded with oxygen, so BeO, Al2O3, Ga2O3, SnO2, SbO5, and PbO2

In addition to the diagonal band of amphoteric compounds, don't forget that H2O is amphoteric too!
