Using a table of standard electrode potentials (such as the one in your textbook), calculate the
standard cell potential for a cell made by placing a zinc electrode in a Zn2+(aq) solution which is
connected by an electrolyte to a Ag+
(aq) solution containing a silver electrode. Show your work.

1. Look up the reduction potential for Zn^2+ + 2e ==> Zn(s) in your text. Reverse the sign.
Add that to the reduction potential for
Ag^+ + e ==> Ag(s)
That potential will be for the reaction of
Zn(s) + 2Ag^+(aq) ==> 2Ag(s) + Zn^2+(aq)

2. reduction potential for the Zn is -.76 for Ag it is .80
so i take the Zn change the sign so it it .76 then i go

.76+.80=1.56 does this sound right?
