Question

which of the following are a.acidic b.basicoxcides: phosphorus pentoxide,sulphur trioxide,sodium oxide, magnesium oxide
​

Answer 1

answer mark as brainlyiest

phosphorous- acidic

sulphur trioxide-acidic

sodium oxide- strong base

magnesiym oxide​on : base

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.
