Question

which of the following is not acidic a) CO2 b) SO2 c) NO2 d) Li2o​

Answer 1

Answer:

Acidic oxides are the oxides of non-metals (Groups 14-17) and these acid ... CO2+H2O→H2CO3. Acidic oxides are known as acid anhydrides (e.g., sulfur dioxide is ... ZnO+2HCl→ZnCl2zincchloride+H2O(basicnature).

Explanation:

Answer 2

Li₂O is not acidic amongst the given options.

• As we move from left to right in a periodic table the nature of the oxide changes from basic to amphoteric and finally acidic.
• Since Lithium lies in the left most corner of the periodic table therefore it is a basic oxide while all the others are acidic oxides.
• The basicity of the oxide is determined by the electro positivity of that element.
• Li is the most electro positive element therefore its oxide is basic while the others are electronegative and their oxides are acidic.
