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).
