Question

Study the following reactions and mark the correct properties shown by water.
$$\eqalign{ & \left( {\text{i}} \right)S{O_3} + {H_2}O \to {H_2}S{O_4} \cr & \left( {{\text{ii}}} \right)C{l_2}{O_7} + {H_2}O \to 2HCl{O_4} \cr & \left( {{\text{iii}}} \right)CaO + {H_2}O \to Ca{\left( {OH} \right)_2} \cr & \left( {{\text{iv}}} \right)N{a_2}O + {H_2}O \to 2NaOH \cr} $$

A. All oxides react with water to give hydroxides.
B. Acidic oxides are formed by metals and basic oxides by non-metals.
C. Non-metal oxides combine with water to form acids while metallic oxides combine with water to form alkalies.  
D. Acidic oxides are stronger than basic oxides since they form strong acids.
Answer :   Non-metal oxides combine with water to form acids while metallic oxides combine with water to form alkalies.
Solution :
Metal oxides are basic in nature while non - metal oxides are acidic in nature. Acidic oxides form acids while basic oxides form alkalies with water.
