    There is no difference in the chemical reactions, what changes in acidic vs basic solutions is the concentration of S-2 ion. H2S is a weak acid, which solution do you think has the most S-2 ions presemt?
    Some metals need a lot of S-2 to form a precipitate, others are so insoluble they need very little. This helps tell which one is which. (Qual scheme)
