Question
Select the acidic oxide from the given options.
- Na2O
- CO
- CO2
- Al2O3
Hint:
CO2 when dissolved in water produces carbonic acid.
The correct answer is: CO2
Acidic oxide produces an acidic solution upon addition to water or when combined with bases, they produce salts. When carbon dioxide is dissolved in water it produces carbonic acid and solution turns blue Litmus red. Litmus test of aqueous carbon dioxide indicate acidic nature of Carbon dioxide.
