Question

This question is about the following oxides
AL2O3
CaO
CO2
CO
MgO
SO2
i) which will react with hydrochloric acid but not with aqueous sodium hydroxide?
ii) Which will react with aq. Sodium Hydroxide but not with HCL?
iii) Which will react with both HCL and aq. Sodium Hydroxide?
iv) Which will react neither with HCL nor with aq. Sodium Hydroxide?

Answer 1

Answer:

i.CaO and MgO

ii.CO2 and SO2

iii.Al2O3

iv.CO

Explanation:

i. CaO and MgO are metal oxides. They are basic in nature

Basic oxides reacts with acid to give salt and water.

ii. CO2 and SO2 are non metal oxides. They are acidic in nature.

acidic oxides reacts with Base to give salt and water.

iii. Al2O3 is Amphoteric oxide. They show characteristics of both acidic and basic oxides.

iv.CO is a neutral oxide. They are neither acidic nor basic.
