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. | Brown colour gas evolved. | Nitrate or Bromide may be present. |
| Added copper turnings. | No effect. | Bromide may be present. |
Confirmatory Test:-
| Experiment | Observation | Inference |
| Added dilute nitric acid and silver nitrate solution. | A pale yellow precipitate formed. | Bromide confirmed. |
Chemical Equations:-
Ionic equation:-
Ag+(aq) + Br–(aq)–> AgBr(s)(yellow)
