Consider the following qualitative analysis scenario and then classify what type(s) of qualitative analysis principle is/are being used. More than one choice may be correct. Select all answers that apply. Both Mn2 and Sn4 can be precipitated by sulfide. However, they can be quantitatively separated by adding acid to raise the [H ] until MnS(s) dissolves while SnS2(s) remains precipitated.
Selective precipitation, fractional precipitation, amphoteric precipitate solubilization, competitive equilibrium solubilization: anioin protonation, competitive equilibrium solubilization: cation compexation, and selective oxidation/reduction
