Problem: Bronze is a solid solution of Cu(s) and Sn(s); solutions of metals like this that are solids are called alloys. There is a range of compositions over which the solution is considered a bronze. Bronzes are stronger and harder than either copper or tin alone.The reaction below is an example of a reaction you could do to remove all the tin from this bronze to leave a pure copper sample. Complete the explanation.Sn(s) + 2HCl(aq)     SnCl2(aq) + H2(g)According to the Activity Series of Metals Sn is ______ H and Cu is ______ it. That is, Sn can be _______ to _____ by HCl(aq), but Cu(s) cannot. We can treat bronze with HCl(aq) to remove Sn as _______ and leave a pure Cu sample.Options:    below      Sn2+(aq)      above       oxidized      Sn2+(aq)

Problem Details

Bronze is a solid solution of Cu(s) and Sn(s); solutions of metals like this that are solids are called alloys. There is a range of compositions over which the solution is considered a bronze. Bronzes are stronger and harder than either copper or tin alone.


The reaction below is an example of a reaction you could do to remove all the tin from this bronze to leave a pure copper sample. Complete the explanation.

Sn(s) + 2HCl(aq)     SnCl2(aq) + H2(g)

According to the Activity Series of Metals Sn is ______ H and Cu is ______ it. That is, Sn can be _______ to _____ by HCl(aq), but Cu(s) cannot. We can treat bronze with HCl(aq) to remove Sn as _______ and leave a pure Cu sample.

Options:    below      Sn2+(aq)      above       oxidized      Sn2+(aq)
