Explain the function of the aluminum wire and the mercury II chloride when testing for tin?

when testing for antimony, what reagent prevents tin from reacting with the H2S to form SnS2?

What reagent is used to identify copper and explain its function.

  • Chemistry -

    The Al wire reduces any Sn^4+ to Sn^2 which forms Hg2Cl2 with HgCl2.

    Shouldn't you be looking for these answers in your text and/or notes.
