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 |
| Smelled the salt. | No Ammonical smell. | Ammonium absent. |
| Added dilute hydrochloric acid to the original solution. | No Effect. | Lead(II) may be present. |
| Added hydrogen disulphide, hydrochloric acid to the original solution. | No Effect. | Pb(II), Cu(II) , As(III) absent. |
| Added dilute hydrochloric acid, concentrated nitric acid, and boiled solution. Then cooled it and added solid ammonium hydroxide. | No Effect. | Al(III) ,Fe(III) absent. |
| Passed Hydrogen disulphide gas through the above formed solution. | No Effect. | Zn (II) ,Mn(II), Ni(II), Co(II) absent. |
| Added ammonium carbonate to above solution. | No Effect. | Mg (II) may be present. |
Confirmatory Test:-
| Experiment | Observation | Inference |
| Added ammonium chloride, ammonium hydroxide and disodium hydrogen phosphate to the original solution. | White precipitate is formed. | Mg(II) Confirmed. |
Chemical Equations:-
Ionic equation:-
Mg2+ + HPO42-(aq) + NH4+(aq) –> Mg(NH4)PO4(white) + H+

Please upload chemical equation for Acidic radical also
Salt+ Ba(NO3)2 gives white ppt
(SO4)2- confirmed
MgSO4+ BaCl2-—> MgCl2 + BaSO4↓
Tell me magnesium nitrate test please
