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. | Violet colour gas evolved. | Iodide may be present. |
Confirmatory Test:-
| Experiment | Observation | Inference |
| Added dilute nitric acid and silver nitrate solution | A pale yellow precipitate formed. | Iodide confirmed. |
Chemical Equations:-
Ionic equation:-
Ag+(aq) + I–(aq) –> AgI(s)(yellow)
