  1. Making Galvanic Cells Lab 3) The salt bridge allows the cell to continue to function. K+ or NO3– can move into one of the half cells to balance the charge created by + metal ions forming or leaving solution. 4) No. We did not get the same values in the lab

  2. Electron flow Cu – Zn cell Zn  Zn2+ + 2e– (oxidation - LEO) Cu2+ + 2e–  Cu (reduction - GER) Cu2++ZnCu+Zn2+ Cu (+) Salt bridge Zn (–) Cu2+ Zn2+

  3. Electron flow Al – Zn cell Zn2+ + 2e–  Zn (reduction - GER) Al  Al3+ + 3e– (oxidation - LEO) 2Al+3Zn2+  2Al3++3Zn Al (–) Salt bridge Zn (+) Al3+ Zn2+
