What are the examples of amphoteric & acidic oxides of metal?

There are substances that can only act as an acid and those that can only act as a base. However, there are also substances that can do both - these are called amphoteric substances. In this lesson, we will learn all about the amphoteric substances. read more

Al 2 O 3 is an example of an amphoteric oxide. Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. Amphoteric oxides include lead oxide and zinc oxide, among many others. read more

Examples of Amphoterism. Metal oxides or hydroxides are amphoteric. Whether a metal compound acts as an acid or a base depends on the oxide oxidation state. Sulfuric acid (H 2 SO 4) is an acid in water, but is amphoteric in superacids. Amphiprotic molecules, such as amino acids and proteins, are amphoteric. read more

Examples of Amphoteric Substances Besides water, substances that can donate and accept protons, like the bicarbonate ion, are amphoteric. Other amphoteric substances can be formed from the oxides and hydroxides of metals like beryllium, zinc, and lead. read more
