AIM: – To identify the given inorganic compound for its acidic and basic radical.
APPARATUS:- Chemical Reagent, Test Tube, Test Tube holder, Spatula
PROCEDURE:-
Preliminary Test:-
| Experiment | Observation | Inference |
| Added dilute sulphuric acid to given salt. | Gas with brisk effervescence evolved. | Carbonate may be present. |
Confirmatory Test:-
| Experiment | Observation | Inference |
| Pass the above-evolved gas through lime water. | Lime water turns milky. | Carbonate confirmed. |
Chemical Equations:-
Ionic equation:-
CO32-(s) + 2H+(aq) –>H2O(l) + CO2(g)
CO2(g) + Ca(OH)2(aq) –> CaCO3(s)(milky) + H2O(l)

This website is too good
S+dil Hcl (no brisk effervescence ) .priliminary for carbonate
How do we test for carbonate if sodium extract of given salt is prepared?
Confirmatory test ?????
You saved me a night before my practical exam
You just saved me!!
