Aluminium oxide is amphoteric

the verdict
SUPPORTED
the evidence backs this
Recorded sources
5 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that aluminium oxide is amphoteric?

Yes. Multiple authoritative reference texts and peer-reviewed scientific studies confirm that aluminium oxide is amphoteric, meaning it exhibits both acidic and basic properties and is soluble in both acids and alkalis.
