LEFT silver (Ag) magnesium RIGHT copper (Cu) zinc (Zn) VOLTAGE +0.43 -1.62 MACROSCOPIC OBSERVATIONS Purple right-side solution and metal warn; left side metal has deposits. Right side metal warns away; left side has deposits. MICROSCOPIC OBSERVATIONS Left side electrons flow downward, attracting additional Ag atoms to join the surface, while right side electrons travel upward, lonizing and dispersing the metal atoms into the solution. AS LEFT SIDE INFERENCES cathode, reduction, Ag+1+le-Ago oxidation, anode, Mg0 --> Mg+2 +20- RIGHT SIDE INFERENCES anode, oxidation, CuO --> Cu+2+2e- reduction, cathode, Zn2+ +2e---> Zn
