Question

Rank the following metals by ease of reduction, starting with the easiest to reduce

Ag+, Ni2+, Al3+, Pb2+, Mg2+

________>________>________>________>_________

Rank the following metals by ease of oxidation, starting with the easiest to oxidize

Mg, Ag, Fe, Cu, Cr                

________>________>________>________>_________

For the following reactions state if the reactions are favored in the forward or reverse direction

a) 2Ag+(aq) + Cu(s) à Cu2+(aq)   + 2Ag(s)                       

b) Ni2+(aq) + Sn(s) à Ni(s) + Sn2+(aq)                                  

c) Mg(s) + Fe2+(aq) à Mg2+(aq) + Fe(s)                                    

d) Pb(s) + Zn2+(aq) à Zn(s) + Pb2+(aq)                                                

Explanation / Answer

1.

Ag+, Ni2+, Al3+, Pb2+, Mg2+

___Mg+2_____>____Al+3____>____Ni+2____>___Pb+2_____>_____Ag+____

2.Mg, Ag, Fe, Cu, Cr                

__Mg______>___Cr_____>____Fe____>___Cu_____>___Ag______

a) 2Ag+(aq) + Cu(s) --------> Cu2+(aq)   + 2Ag(s)      reverse direction

b) Ni2+(aq) + Sn(s) ---------> Ni(s) + Sn2+(aq)   reverse direction

c) Mg(s) + Fe2+(aq) -------->Mg2+(aq) + Fe(s)     forward reaction

d) Pb(s) + Zn2+(aq) à Zn(s) + Pb2+(aq)             reverse reaction
