Study the following reactions and mark the correct properties shown by water. (i) SO3 + H2O → H2SO4 (ii) Cl2O7 + H2O →2HClO4 (iii) CaO + H2O →Ca(OH)2 (iv) Na2O + H2O →2NaOH
A.All oxides react with water to give hydroxides
B.Acidic oxides are formed by metals and basic
C.Non-metal oxides combine with water to form acids✓ Correct
D.Acidic oxides are stronger than basic oxides since
Explanation
Non-Metal oxides are generally acidic and on reaction with 2 H O , forms acids, Metal oxides are basic and on reaction with 2 H O , forms base (alkali).
