Class 10 Science

Metals Non-metals


To show that metals have high melting point.

Materials Required: Copper or aluminium wire, stand, clamp, Bunsen burner


set for experiment to show high melting point of metal

Observation: The metal wire becomes very hot; as can be shown by the falling of nail.

Conclusion: Metals have high melting point.


To show the nature of metallic oxide and non-metallic oxide.

Materials Required: Magnesium ribbon, sulphur powder, tongs, gas jar, litmus paper, etc.


Observation: There is no effect on blue litmus paper, but red litmus paper turns blue when it is dipped in aqueous solution of magnesium oxide.

Conclusion: Magnesium oxide is basic in nature. This means that metal oxides are basic in nature.

Procedure for Sulphur Powder:

Observation: Blue litmus paper turns red in presence of sulphur dioxide.

Conclusion: Non-metallic oxides are acidic in nature.


To show displacement reaction

Materials Required: Test tubes, copper sulphate solution, iron sulphate solution, copper wire, iron nail, corks, test tube stand


set up for experiment on displacement reaction

Observation: The colour of copper sulphate fades away and iron nail acquires a brown deposit. No change is observed in the test tube which has iron sulphate solution.

Conclusion: Iron displaces copper from copper sulphate solution. But copper is unable to displace iron from iron sulphate solution. This happens because iron is more reactive than copper.


To show metal's reaction with dilute acid

Materials Required: Test tube, water bath, cork, stand, clamp, dilute sulphuric acid, zinc granules


set up to show metal's reaction with dilute acid

Observation: Effervescence can be seen in test tube. This shows some chemical reaction taking place. Bubbles can be seen coming from water bath; which shows that some gas is evolving.

Check the nature of gas: Bring a burning matchstick near the bubbles. You will observe that the matchstick burns with a pop sound. This indicates that the evolved gas is hydrogen gas.

Conclusion: When a metal reacts with dilute acid, metal salt and hydrogen gas is formed.
