describe on activity to show the effect of an acid on carbonate and hydrogen carbonate?
Answers
All metal carbonates and hydrogen carbonates react with acids to give a corresponding salt, carbon dioxide, and water. Thus, the reaction can be summarized as: The activity describing the effect of acid on metal carbonates and metal bicarbonates is : ... This indicates that the evolved gas id Carbon-di-oxide.
The activity discriving the reaction of acid with metal carbonates and metal hydrogen carbonate:-
1. Take a small amount of metal carbonate in test tube A and metal bi-carbonate in test tube B.
2. Pour few drops of sulphuric acid in both the test tubes. you will notice evoltion of colourless gas.
3. Pass the evolved gas in both test tube through the lime water eith the help of delivery tube.
4. You will notice that the lime water turn colorless in both the cases. This indicates that the evolved gas carbon-di-oxide.
Example:- ZnCO3 + H2SO4 → ZnSO4 + CO2 + H2O
