Question

What is the nature of oxides of metals and non metals and how can we test it?

Answer 1

oxides of metal are basic and sometimes acidic too and they can be obtained by various implementing methods and the ways to classify the elements for purification is known as metallurgy

Answer 2

$\huge\mathbf{Answer}$

$<b>oxides of metals are basic in nature and the oxides of non-metals are acidic in nature. </b>$

$<b><u> Activity to test the nature of non-metal oxide </u></b>$

Take a small amount of powdered sulphur in a deflagrating spoon and heat it. as soon as it starts heating up or burning , take it to a glass tumbler and cover the tumbler with a lid. remove the spoon after some time and add a small amount of water in it. shake the solution well. test the solution with blue and red litmus . hence, it will change blue litmus to red . therefore, the oxides of non-metals are acidic in nature.

$<b><u> Activity to test the nature of metal oxide </u></b>$

Burn Magnesium ribbon and collect the ash after burning it , which is magnesium oxide ( MgO ) and dissolve it in a small quantity of water and test it with a blue litmus and a red litmus paper. hence, it changes the red litmus paper to blue , it indicates that the solution is basic in nature. therefore, the nature of metal oxides are basic in nature.
