A student does an experiment to determine wether titanium metal should be placed on the activity series chart. He places newly cleaned pieces of titanium into solutions of nickel(II) nitrate, lead(II)nitrate and magnesium nitrate. He finds that teh titanium reacts with nickel (II) nitrate and lead(II) nitatre solutions, but not with the magnesium nitrate solution. From this information, place titanium in the activity series in position realtive to these ions.
