Examples of Amphoteric Solids

Amphoteric solids are substances that can act as both acids and bases. They can donate or accept protons depending on the reaction conditions. Here are some examples of amphoteric solids:

1. Aluminum Oxide (Al2O3) - Aluminum oxide can react with both acids and bases. It can react with strong acids to form aluminum salts and with strong bases to form aluminates.

2. Zinc Oxide (ZnO) - Zinc oxide exhibits amphoteric properties and can react with both acids and bases. It can form zincates with strong bases and zinc salts with strong acids.

3. Lead Oxide (PbO) - Lead oxide is another example of an amphoteric solid. It can react with both acids and bases, demonstrating its amphoteric nature.

These examples illustrate the amphoteric nature of certain solid substances, showcasing their ability to exhibit acidic or basic behavior depending on the reaction conditions.
