Anyaction that makes [Zn2+] smaller than[Pb2+].
Any action that makes [Zn2+]larger than [Pb2+].
Adding some concentratedZn(C2H3O2)2 solution tothe Zn2+/Zn couple.
Anyaction that makes Q > 1.0.
Addingsome concentratedPb(C2H3O2)2 solution tothe Pb2+/Pb couple.
Anyaction that makes log Q positive.
Any action that makes log Qnegative.
Any action that makes Q <1.0.
