प्रश्न
With the help of examples, describe how metal oxides differ from non-metal oxides.
उत्तर
Metal oxides are generally basic in nature, which can turn red litmus solution to blue while non-metal oxides are generally acidic in nature, which can turn blue litmus solution to red. For example, sodium oxide and potassium oxide are metal oxides which are basic in nature; carbon dioxide and sulphur dioxide are non-metal oxides which are acidic in nature.
