Question

Plzzzz
it's urgent
answer:
how will you show that when an acid react with metal carbonate the gas evolve in carbon dioxide

Answer 1

Heya !!!



here is your answer !!!


when the acid react with carbonate IT form corresponding salt carbon dioxide and water.


for example :-


HCl + CaCO3 ==> CaCl2 + H20 + Co2


======================= ============



your question is how can we test the presence of carbon dioxide am I right ??


ok !!



let me explain !!!


to know the taste of carbon dioxide we have to do an experiment :-


here in prosedure of experiment;-



1) take the quicklime ( CaO )

2) when the acid react with carbonate there is release of carbon dioxide gas



3) so to know the presence of gas release the gas in Quicklime !!!



4 ) after releasing gas into quicklime you observe that there is formation of calcium carbonate ( CaCO3 )



So here is the reaction that show presence of carbon dioxide in CaO reaction



CaO + Co2 ==== => CaCO3



here , we take the carbon dioxide from acid and carbonate reaction.




now this experiment show the presence of carbon dioxide in carbonate and acid reaction




hope it helps you dear!!!



thanks !!!
