. Give reason for the following a Aluminium oxide is considered


as an amphoteric oxide.(b) ionic compounds conduct electricity in molten state

Best Answer

Explanation:

a) Amphoteric oxide: Those metal oxide which reacts with acids as well as bases to produce salts and water.

 Aluminum oxide reacts with acids as well as bases to produce salts and water. '

Al2O3 + 6HCl  2 AlCl3 + 3H2O

Al2O3 + 2 NaOH 2NaAlO2 +H2O  

Hence it is amphoteric in nature.

      (b)  Ionic compounds conduct electricity in molten state because ions are free to move in molten state.

Final Answer:

Hence a)   Aluminum oxide reacts with acids as well as bases to produce salts and water so it is amphoteric in nature.

b) Ionic compounds conduct electricity in molten state because ions are free to move in molten state.
