Define amphoteric oxide. Give an example

Sure!

Step 1: Understand the question The question is asking for the definition of an amphoteric oxide and an example of one.

Step 2: Define amphoteric oxide An amphoteric oxide is a type of oxide that can react with both acids and bases. It can act as both an acid and a base, depending on the reaction conditions.

Step 3: Give an example of an amphoteric oxide One example of an amphoteric oxide is aluminum oxide (Al2O3). It can react with both acids and bases. When it reacts with an acid, it acts as a base and forms a salt. When it reacts with a base, it acts as an acid and forms a salt and water.

So, in summary, an amphoteric oxide is a type of oxide that can react with both acids and bases. An example of an amphoteric oxide is aluminum oxide (Al2O3).
