Question

give an activity to show the reaction of acid with metal.​

Answer 1

Answer:

hlo here is ur answer

Explanation:

Procedure :

Set the apparatus as shown in figure.

Take about 10 ml of dilute HCl in a test tube and add a few zinc granules to it.

We will observe the formation of gas bubbles on the surface of zinc granules.

Pass the gas being evolved through the soap water.

Gas filled bubbles are formed in the soap solution which rise into the air.

Bring a burning candle near the gas filled bubbles.

The gas present in a soap bubble burns with a ‘pop’ sound.

Result:

Only ‘hydrogen’ gas burns making a ‘pop’ sound.

So we will notice that gas evolved is { H }_{ 2 }.



Additional Experiment:

Repeat the above experiment with H_{2}SO_{4} and HN{{O}_{3}}.

We observe the same observation of the HCl experiment.

Conclusion : From the above activities we can conclude that when acid reacts with metal, ${ H }_{ 2 }$gas is evolved.

Answer 2

Reaction of acid with metal:-

Aim: To prove acid reacts with metal.

Materials required: Test tube, zinc granules, dilute HCl, delivery tube glass through candle soap water.

Procedure: Take 20ml of dilute HCl and add zinc to it then the gas being evolved is passed through soap water .Bring a burning candle near gas filled babble you will notice the gas involved with a pop-sound concluding it has hydrogen.

⇒This activity shows that metal carbonates and metal hydrogen carbonate react with acids to form salt, CO2 and water.
