Suppose you have Q as a mixure of two inorganic salts. The mixture was dissolved in water and filtered.
Test were carried out on both the filtrate and residue.
(1)When a portion of the filtrate was poured into dilute HCL + BaCL2(aq), there was no visible reaction. What would be the inference?
(2) When portion of filtrate was poured into dilute HNO3 + AgNO3(aq) + excess dilute. NH3(aq), there was no visible reaction. What would be the inference?
The Attempt at a Solution
.Suppose there was white precipate insoluble in excess of dilute HCl+BaCl2(aq), I would have suggested that SO42- ion is present but in this case, there is nothing like that, so what would the inference be?
The same apply to (2). Suppose, there was a white precipitate soluble in excess as the portion of filtrate was added to dilute HNO3+ AgNO3(aq). NH3(aq) then I would have suggested that Cl- ion but there was not reaction.
