hey buddy
Explanation:
To show the reaction of acids with metals.
Required Materials : 1. Test tube 2. Delivery tube 3. Glass trough 4. candle 5. Soap water 6. Dil. HCl 7. Zinc granules.
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:
The activity describing the effect of acid on metal carbonates and metal bicarbonates is : Take small amount of metal carbonate (Zinc Carbonate) in Test tube A and metal bicarbonate (Zinc hydrogen carnonate) in test tube B. Pour few drops of Sulphuric acid in both the Test Tubes. You will notice evolution of a colourless gas.
