And this changes the concentration of our inside and outside. So this is our oxidation reaction, where our potassium is oxidized, and our reduction reaction, where the potassium accepts the electrons form of the solid. Now, if we if we want to find the net rebus reaction, we simply add these two guys up the east cancel, the K solids cancel, and we are left with K plus inside and K plus outside. Notice the reactants is the inside. This is where we begin, and this guy is the outside. This is where we end because electrons travel this way, but the ions want to travel this way because we have more ions on the outside on the inside than the outside.
