conditions regarding amphoteric compounds

[805754009]

In lecture it was mentioned that amphoteric compounds could react with acids and bases depending on the conditions. What conditions are being referred to here? It's slightly difficult for me to conceptually understand.

I think that the conditions being referred to are the certain solutions that the amphoteric compound is being mixed with. For instance, H2O is considered an amphoteric compound, and when H2O is mixed with a strong acid, H2O becomes a base that accepts the H+ being donated by the strong acid, such as HCl. However, H2O can also be an acid when mixed with a strong base such as KOH. H2O will donate a H+ to the OH- in KOH, making H2O the acid in this situation. Amphoteric compounds will act as the acid or base depending on the solution they are mixed will, which is the conditions.
