This electron then travels via the conductor into this second electrode, a different metal. Now, inside this electrode, this electron reacts with this y plus ion that is taken up into the electrode and they react to form our Y solid. Now, notice one type of reaction occurred that deals with X in this beaker. And a second type of reaction, a different reaction occurred in beaker Two. And this difference created something called a cell voltage. And we saw that once again, on the standing conditions, we use this formula, and on the nonstanding conditions, we use this formula.
