Now, we know to lose these interactions, we have to input a certain amount of energy. And that process requires energy, but we know this process does not require energy. So how is this actually fixed? How is this problem actually fixed? Well, it turns out that if we zoom in on this section, so let's suppose one of these potassium ions makes its way into this region and it loses these water molecules. So what exactly happens to that potassium ion as it travels through this section?
