Question

Is metal oxide acidic or basic? support the answer with a chemical equation.

Answer 1

Non-metals react with oxygen in the air to produce non-metal oxides. Here are two examples for the non-metals carbon and sulphur. Non-metal oxides such as sulphur dioxide and nitrogen oxide are responsible for acid rain. They dissolve in the water in the clouds to form acidic solutions.

Al2O3 is not acidic it is amphoteric , meaning it acts as both acidic and basic oxides depending on the reaction , this is one of Aluminium's​ unique property.Na2O is basic because it belongs to the most metallic group metals that is the Alkali metal group .Notice the group of metals itself is called Alkali metals ...
