And this difference in reactions creates something called electric potential, also known as a cell voltage. And we saw that understanding conditions of 1 bar pressure and one molar concentration, we can find find our cell voltage by using this formula where we first find our cell voltage of the anode and then subtract that from the capital. And these values can be looked up on a reduction half reaction table. Now, what happens when our conditions are not standard? Well, then we have to use this formula. And we saw that this formula is called Nurse Formula.
