Question

How do acids react with carbonates and metal hydrogen carbonates with activity amd diagram​

Answer 1

Answer:

Reaction occurring in the above activity :

Test tube 'A' Na2CO3(s)+2HCl(aq)→2NACl(aq)+CO2(g)+H2O(l)

Test tube 'B' NaHCO3(s)+HCl(aq)→NaCl(aq)+CO2(g)+H2O(l)

On passing the gas evolved through the lime water :

Ca(OH)2(aq)lime water+CO2(g)→CaCO3(s)white ppt.(milkiness)+H2O

But on passing excess CO2 gas through the lime water, milkiness disappears due to the formation of soluble CaHCO3

CaCO3+CO2+H2O→Ca(HCO3)2(aq)Calcium hydrogen-carbonate

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