Question

what are amphoteric oxide?give 2 example?

Answer 1

Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water.
Examples: aluminium oxide and zinc oxide.

Answer 2

Answer:

• ‘Oxides of metals’ that is having both the acidic behaviour as well as basic behaviour are referred to as amphoteric oxides.
• Those metallic oxides are react with the acids and also to the base to produce water and salt.
• Examples of ‘Amphoteric oxides’ are zinc oxide and aluminium oxide.

• Most of the metals such as zinc, copper, lead and some other elements reacts with ‘oxygen to form metal oxides’.
• Amphoteric nature of the metal oxides are completely depends upon the ‘oxidation state’ of the metals in that metal oxides.
