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 smell of burning sulphur evolved. | Sulphite may be present. |
Confirmatory Test:-
| Experiment | Observation | Inference |
| Add barium chloride to the salt. | A white precipitate of barium sulphite formed which dissolved in excess hydrochloric acid to give a clear colourless solution. | Sulphite confirmed. |
Chemical Equations:-
Ionic equation:-
Ba2+(aq) + SO32-(aq) –> BaSO3(s)
