When do I use E_cell = E_cathode − E_anode in Electrochemistry, and what does it mean?
standard cell EMF from electrode potentials.
E_cell = E_cathode − E_anode — standard cell EMF from electrode potentials. Use it when: standard conditions. Always check the condition holds before plugging in numbers.
Key point
E_cell = E_cathode − E_anode
