Flipping the anode

Postby MariaJohn1D » Sun Mar 15, 2020 6:48 am

why do we flip anode in cell notation?

in terms of the equations representing galvanic cells, we'd flip the anode because all of the standard cell equations are in the form of reduction, which is the process that is occurring at the cathode. We'd flip the anode in a chemical equation because doing so, we'd represent the reaction occurring at the anode, oxidation (which is the "opposite" of reduction).

Since all the standard cell equations are written as reduction (which coincide with the cathodes), then the anode must be flipped to get the oxidation half reaction.

All half equations are written as reduction, so we would flip the anode in order to make the reaction a redox reaction.

Flipping the anode identifies it as an oxidation reaction and allows us to cancels out the electrons with the cathode side when writing the equation.
