Question

15. (a) What do you understand by amphoteric oxide ?
(b) Give the balanced equations for the reaction with
two different amphoteric oxides with a caustic alkali.
(c) Name the products formed.
for the following conversions​

Answer 1

Answer:

1. ) an amphoteric compound is a molecule or ion that can react both as an acid and as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. ... Amphoteric oxides include lead oxide and zinc oxide, among many others.

2.) here is your answer

Amphoteric oxide = Al203

caustic alkali = NaOH

Reaction:-

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

3.) The product formed is Sodium aluminate(2NaAlO2)
