In which both the oxides are amphoteric

To determine which oxides are amphoteric, we need to understand what it means for an oxide to be amphoteric. An amphoteric oxide is one that can act as both an acid and a base.

First, let's identify the oxides in question. We'll call them Oxide A and Oxide B.

To determine if Oxide A is amphoteric, we need to see if it can react with both acids and bases. We can test this by adding Oxide A to an acidic solution and observing if it reacts to neutralize the acid. If it does, then Oxide A is acting as a base. Similarly, we can add Oxide A to a basic solution and see if it reacts to neutralize the base. If it does, then Oxide A is acting as an acid. If Oxide A reacts with both the acid and the base, then it is amphoteric.

Next, we repeat the same process for Oxide B. We add Oxide B to an acidic solution and observe if it reacts as a base, and then add it to a basic solution to see if it reacts as an acid. If Oxide B reacts with both the acid and the base, then it is also amphoteric.

In conclusion, to determine if both Oxide A and Oxide B are amphoteric, we need to test their reactions with both acids and bases. If they react with both, then they are amphoteric oxides.
