Cell Diagrams

Postby Lily Guo 1D » Tue Feb 20, 2018 9:47 pm

Does it matter what order the items in the anode side and cathode side of a cell diagram are written? For example, if you have Cl2 (g) and HCl (aq) on the anode side, would it make a difference if you wrote Cl2 (g) | HCl (aq) or if you wrote HCl (aq) | Cl2 (g) for the anode?

Hi, Lily,
Yes, you always need to write the species in the order of reactants/product. So, if it's an anode (oxidation), you will write: HCl/Cl2.

For cell diagram, within each half part, electrode and solids are written far away from the salt bridge, followed by liquid, gas and aqueous solution. Within each phase, orders are not strictly defined, but people tend to put in the order of reactant to product.
