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. | No effect. | Carbonate, sulphide , sulphite, nitrate absent. |
| Added concentrated sulphuric acid to given salt. | No effect. | Nitrate, Bromide, Chloride, Acetate, absent. Sulphate or phosphate may be present. |
Confirmatory Test:-
| Experiment | Observation | Inference |
| Added barium chloride solution. | White coloured precipitate is formed. | Sulphate confirmed. |
Chemical Equations:-
Ionic equation:-
Ba2+(aq) + SO42-(aq) ==> BaSO4(s)(white)
