Half-Reactions of a Reaction with one Reactant

Postby Christiana2D » Sat Mar 17, 2018 8:30 pm

In example 14.8 on page 586 of the book, for a reaction with one reactant they define one of the half reactions as the overall reaction itself. What is the reasoning behind this? Or, how would you split a reaction with only one reactant into half reactions?

There are two reactants - Ag and Cl. The example is a little strangely formatted, but it gives us in the little diagram that the two electrodes are AgCl and Ag, and that the Ag electrode is oxidized, so it produces Ag+. The other electrode, AgCl, picks up electrons and produces Ag and Cl-.
