Problem

To determine the position of three metals in a reactivity series, the metals were placed in different aqueous solutions of metal ions. The table summarizes whether a reaction occurred.
MetalAg+(aq)\text{Ag}^+(\text{aq})Pb2+(aq)\text{Pb}^{2+}(\text{aq})Ni2+(aq)\text{Ni}^{2+}(\text{aq})
Ag(s)\text{Ag}(\text{s})—No reactionNo reaction
Pb(s)\text{Pb}(\text{s})Reaction—No reaction
Ni(s)\text{Ni}(\text{s})ReactionReaction—
Deduce the ionic equations for the three reactions that take place. Use this information to place silver, lead, and nickel in a reactivity series, with the strongest reducing agent first. Explain your reasoning.
