1.	Study the following reactions and mark the correct properties shown by water. (i) SO_(3) + H_(2)O to H_(2)SO_(4) (ii) CI_(2)O_(7) + H_(2)O to 2HCIO_(4) (iii)CaO + H_(2)O to Ca(OH)_(2)(iv) Na_(2)O + H_(2)O to 2NaOH
Answer» All oxides react with water to give hydroxides. Acidic oxides are formed by metals and basic oxides by non-metals. Non - metal oxides COMBINE with water to FORM acids while METALLIC oxides combine with water to form ALKALIES. Acidic oxides are stronger than basic oxides since they form STRONG acids. Solution :Acidic oxides form acids while basic oxides form alkalies with water.
