The Nernst equation on the right is related to the Goldman equation but it allows you to calculate the membrane potential for individual ions. Let’s give it a try for the potassium ion and the sodium ion. The figure on the right gives you the information you need for the Nernst equation.
What is the Nernst potential associated with the potassium ion?
