Understanding cell diagrams

Postby josephyim1L » Thu Feb 28, 2019 2:34 pm

What is the role of the inert metal and how should it be put into the skeletal diagrams? Ex: Pt(s)

It is used if one(or both) if the oxidizing(or reducing ) agents are not conductors. Thus, if they are not a metal or if they aqueous ions, before and after the reaction, you need an inert metal such at Pt, to be the electrode and transfer electrons. In the cell diagram, you would just add a vertical line next to the agents that are not conductors and then write the inert metal.

if you didnt have the inert metal there, how would the electrons transfer? they cannot just jump from an aqueous solution over to the other beaker..
