Question

Write the equation when aluminium oxide reacts with base(naoh).

Answer 1

Al2O3 + 2NaOH ---> 2NaAlO2 + H2O
Aluminum oxide reacts with sodium hydroxide to produce sodium aluminate and water. This reaction takes place at a temperature of 900-1100°C.

Answer 2

Explanation:

When aluminium oxide reacts with base sodium hydroxide (NaOH) then both these compounds chemically react together and result in the formation of sodium aluminate and water.

The reaction equation for the same is as follows.

         $Al_{2}O_{3} + NaOH \rightarrow 2NaAlO_{2} + H_{2}O$

So basically, a salt and water is obtained in this reaction in which aluminium oxide acts as an acid.
