QUESTION 7
Which of the following are CORRECT concerning the measurement of the potential difference across the potassium ion selective membrane?
The driving force for the diffusion of K* across the membrane is the favorable free energy change that occurs when K* is solvated by water.
The potential difference across the membrane is measured by two reference electrodes.
Eouter is constant.
At equilibrium, the net change in free energy for the diffusion of K* ions across the membrane is greater than 1.
