Question

K. Consider the oxides Li2O, CO2, B2o3
a. Which oxide would you expect to be
the most basic?
b. Which oxide would be the most acidic?
c. Give the formula of an amphoteric
oxide.​

Answer 1

Answer: The answer of the c sub question is Al2O3

Explanation:

Aluminium oxide is one of the most acidic amphoteric oxides and thus is a good example.

Answer 2

Explanation:

For the first case since the metal oxides are always basic in nature and basic nature also depends on the formation of salt when the metal compound reacts with acid and among the following only Li2O is basic in nature.

For the second case the nonmetallic oxide is acidic and also in solution it acts as acid while itself it is not acidic and it is acidic because it can be in equilibrium with water.So, from the following CO2 is acidic in nature.

While the B2O3 is amphoteric oxide.
