Write two chemical equations to show that al2o3 is an amphoteric oxide
Answers
If yes please mark as brainliest.
Answer:
Al₂O₃ reacts with both acids and bases, as per the given following chemical equations.
Al₂O₃ + 6HCl ---> 2AlCl₃ + 3H₂O (Basic Nature)
Al₂O₃ + 2NaOH ---> 2NaAlO₂ + H₂O (Basic Nature)
Explanation:
Amphoteric oxides are oxides that may behave both acidic and basic.
An oxide is referred to as amphoteric if it interacts with both acids and bases.
An oxide known as an amphoteric oxide may function as both an acid and a base used in the production of salt and water.
A chemical species' available oxidation states are predicated on amphoterism.
Metals in various oxidation states produce amphoteric oxides and hydroxides.
Al₂O₃ and HCl combine to form aluminium chloride, a salt, and water as a byproduct.
Similar to this, when a strong base like NaOH reacts with an oxide like Al₂O₃ , Sodium Aluminate is created as salt and water.
As Al₂O₃ acts both acidic and basic as per the above equations, Hence it is a amphoteric oxide.
