Question

which of the following are (a) acidic (b) basic oxides? phosphorus pentoxide,sulphur trioxide,sodium oxide,magnesiym oxide​

Answer 1

Answer:

phosphorous- acidic

sulphurtrioxide-acidic

sodium oxide- strong base

magnesiym oxide​on : base

Answer 2

ANSWER:

Phosphorous pentoxide, Sulphur trioxide are acidic oxides whereas Sodium oxide and magnesium oxide are basic oxides.

EXPLANATION:    

Phosphorous pentoxide is the oxides of Phosphorous and is acidic in nature as they undergo exothermic hydrolysis. As Sulphur trioxide on its reaction with water gives sulfuric acid, it is an acidic oxide.

Sodium Oxide contains 02- ion and this indicates that Sodium Oxide is strong base and has high possibilities of combining with hydrogen ions. Magnesium Oxide on its reaction with water accepts protons and thus termed it as a base.
