Interpreting cell diagram

Postby 005199302 » Sun Feb 24, 2019 7:41 pm

If given a cell diagram such as this:

Ag(s) I AgI(S) I I-(aq) II....

How would I know if Ag + I make up the reactants or the products for the anode half reaction of the cell?

Cell diagrams always write the left portion of the battery, the anode, first. So, our product has to have silver in a state with a higher charge (Anode has the oxidation reaction). If Ag is becoming AgI, its charge goes from neutral to +1. As a result, we know that AgI has to be our product.
Hope this helps!
