Question

give the balance equation for the reaction with two different amphoteric oxides with a caustic alkali and name the product formed

Answer 1

$heya...$

here is your answer

Amphoteric oxide = Al203

caustic alkali = NaOH

Reaction:-

Al2O3 + 2NaOH-----> 2NaAlO2 + H2O

The product formed is Sodium aluminate(2NaAlO2)

Answer 2

heya!!!

Two amphoteric oxides are ZnO & Al2O3

caustic alkali is NaOH

$reaction$

Al2O3 + 2NaOH---> 2NaAlO2 + H2O

NaAlO2 is sodium aluminate

ZnO + 2NaOH------> Na2ZnO3 + H2O

sodium zincate
