g. Using your experimental results, explain why Zn(s) will reduce Cu?, Ag and H+ ions, but...
Does the ordering of activity series Mg, Zn, Fe, Cu, Ag agree with the ionization energies of the elements? Why or why not? selecuul UI e vunum 14. Since the activity series describes the propensity for a metal to lose electrons one might think that ionization energies could predict the activity series. Ionization energies are measured in the gas phase and have the following values for the metals used in this laboratory: Reaction Ag (5) ► Agt (g) + 1...
