Writing the Cell Diagram for Galvanic Cells

Postby Erika Gonzalez 1F » Sun Feb 12, 2017 8:15 pm

Can someone explain how to write the cell diagram? Does the anode go first then the salt bridge and then the cathode along with the metal?

Ex: Zn(s)|Zn^2+(aq)||NO3-(aq)|NO2(g)|Pt(s)

Yes you're exactly right. It goes the half reaction in the cathode(the reduction reaction) then the salt bridge then the half reaction in the anode(the oxidation reaction). If one of the half reactions does not have a solid then add pt(s) on the outside of that half reaction. Also if the two components of a half reaction are of the same phase, then you can use a comma to separate them.
