Which of the following is a proper notation for the voltaic cell consisting of of one half-cell with a zinc electrode in 1 M Zn(NO3)2 solution and the other half-cell with a lead electrode in 1 MPb(NO3)2 solution and a KNO3 salt bridge.
Pb2+(1 M) | Pb(s) || Zn(s) | Zn2+(1 M)
Zn2+(1 M) | Zn(s) || Pb(s) | Pb2+(1 M)
Pb(s) | Pb2+(1 M) || Zn2+(1 M) | Zn(s)
Zn(s) | Zn2+(1 M) || Pb2+(1 M) | Pb(s)
Homework Answers
Zn(s) ---------------> Zn^2+ (aq) + 2e^- ( oxidation half reaction)
Pb^2+ (aq) + 2e^- -------> Pb(s) ( reduction half reaction)
------------------------------------------------------
Zn(s) + Pb^2+ (aq) -------------> Zn^2+ (aq) + Pb(s) overall reaction
