The products for the reaction of given oxides with water, the equation for these reactions and the nature of the given oxides (whether acidic, basic or emphoteric) has to be given
Oxides of metals and non-metals may be,
Acidic-exhibits acidic character
Basic-exhibits basic character
Amphoteric-exhibits both acidic and basic character
Neutral-does not exhibit any of the acidic or basic character
Except Beryllium oxide ( ), all the oxides of alkali metals and alkaline earth metal are basic in nature.
None of the oxides of non-metals show basic property.
Oxides of non-metals with higher oxidation number of the main group elements are highly acidic whereas those with lesser oxidation number does not exhibit measurable acidic properties.
Beryllium oxide ( ) and many of the metallic oxides of Group 3A and 4A are amphoteric
Reactions of metal and non-metal oxides:
Similar to the normal acid-base reactions, reactions of acidic oxides with bases and basic oxides with acids produce salt and water as products.
Reaction of basic metallic oxides with water results in metal hydroxides.
Reaction of acidic oxides with water results in formation of acids
