Aluminium reacts with caustic soda to form

1.	Aluminium reacts with caustic soda to form
Answer» ANSWER: Explanation: ⇒ When Aluminium reacts with CAUSTIC Soda (NAOH) gives sodium aluminate and hydrogen gas. ⇒ Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. ⇒ The reaction is HIGHLY exothermic once established and is accompanied by the RAPID evolution of hydrogen gas. The reaction is written as: 2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H2.

Explanation:

⇒ When Aluminium reacts with CAUSTIC Soda (NAOH) gives sodium aluminate and hydrogen gas.

⇒ Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal.

⇒ The reaction is HIGHLY exothermic once established and is accompanied by the RAPID evolution of hydrogen gas.

The reaction is written as: 2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H2.
