E potential

[Karina Kong 2H]

If given to E potentials, is the higher E potential the cathode?

[Brandon Tao 1K]

Yes if it is a galvanic cell

[Rohit Ghosh 4F]

Yes, because the E value represents the reduction potential, flipping it represents the oxidation potential. The higher reduction potential will be the cathode, while the flipped oxidation reaction will be the anode.

[Andrew F 2L]

If you are asked to find the standard potential after figuring out which is the cathode however, do NOT change the sign on the potential value if you are using Ecell= Ecathode- Eanode

[Bryce Ramirez 1J]

You can determine which one is the cathode and which one is the anode by subtracting one from the other, and whichever order of numbers gives you a positive E cell, then the number on the left was the cathode and the one on the right is the anode.

[Celena Kim 2I]

YEs, the more positive E potential would be the cathode while the more negative E potential would be the anode.

[Ryan Yoon 1L]

Yes, a higher E value means that its is a very strong oxidizing agent, meaning that it is the cathode as it is reduced.

[ramiro_romero]

Yes, you want your cell potential to be positive. Therefore, the largest value will be the cathode. Keep in mind the formula, Ecell = E cathode - E anode.

Yes, the cathode is always (I think) the highest Epotential and the lowest one is the anode.
