Which of the following statements are CORRECT? I. Oxides of metals are generally basic. II. Oxides of non-metals are generally acidic. III. Non-metals are generally electro positive. Correct Answer Only I and II 

  • Metallic oxides are basic in nature because they react with dilute acids to form salt and water.
  • Non-metallic oxides are acidic in nature since they react with water to form metal hydroxides which are alkaline in nature
  • Non-metals are generally electronegative in nature because these metal hydroxides release OH- ions in solution.
