A student studied some reactions involving Pb2+ ion, copper(II) ion (Cu2+), and nickel(II)ion (Ni2+). The student first observed the behavior of individual solutions of Pb(NO3)2, copper(II) nitrate, Cu(NO3)2, nickel(II) nitrate, Ni(NO3)2, interacting individually with 1M HCl solution and then individually with 1M sodium hydroxide solution (NaOH). The student also added an aqueous ammonia...
