Tin and Copper from Bronze : metallurgy Reddit
网页What is deposited on the cathode will be whatever is in solution. In this case copper. But this is copper from the CuSO4, not copper from the bronze anode. What is taken out of the bronze can be determined from the galvanic series. In this case, Zinc is the element highest on the galvanic series, so it will dissolve off the anode first.
