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 | Obervation | 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 soda extract and diluted nitric acid and then added Ammonium Molybdate solution. | A canary yellow precipitate formed. | Phosphate confirmed. |
Chemical Equations:-
(NH4)2(NO3)+2Na2(PO4) –> 2(NH4)(PO4)+2Na2(NO3)
