Is Al2O3 acidic or basic?
Aluminum Oxide
Aluminium oxide is amphoteric. It has reactions as both a base and an acid.
Why is Al2O3 written?
When writing a formula, the amount of positive charge from the cations must equal the amount of negative charge from the anions, resulting in no net charge. … If we combine two Al3+ ions and three O2- ions, and use subscripts to indicate the number of each ion in the formula, we obtain Al2O3 as the empirical formula.
