Question
Reagent for each separate cation is not possible. In other words, 'individual comp most likely interfere with one another. Therefore, in the scheme that we will employ, reagent in our samples into group. Each group will then be analyzed for the presence or absence the most common. Each group will then be analyzed for the presence or absence subdivide into smaller groups is by selective precipitation, in which the ions in the precipitate can then be physically separated from those precipitate (solid) settles out and the solution (supernatant) is transferred into a, group is separated into smaller and smaller groups until definitive tests can be emcee of each specific cation. Ans in our qualitative analysis scheme will be organized into groups that we will labeled A the distinction between these groups and the groups of the Periodic Table groups A-D do not necessarily correlate with groups in the Periodic Table. Periodic Table electron configurations that result in similar behaviors of the elements within the grow icings do fall within the same Group in the Periodic Table, Group C for instance, and Groups we use in qualitative analysis are based solely upon the solubility behavior for example, Group A consists of cations that form insoluble chlorides in acidic sol the analysis may require that there be further separations into subgroups. A specificExplanation / Answer
a) The addition of 6M HCl to the solution formed a precipitate. It indicates the presence of Ag+ or Pb2+ in the solution.
b) The white precipitate is washed with hot water and added KI solution to the supernent liquid. It has been observed that there is no precipitate formed. This concludes that there are no other ions present in the resulting solution.
c) AgCl (s) + NH3 (aq) <-------> [Ag(NH3)2]+ (aq) + Cl- (aq)
[Ag(NH3)2]Cl (aq) + HNO3 -------------> AgCl (s) + NH4NO3 (aq)
