When a major portion of the intracellular K+ in frog muscle is reversibly replaced by Na+, the extra Na+ gained by the cells does not show the nuclear magnetic resonance signal that free Na+ does. The data contradict the membrane theory but are in accord with the concept that the bulk of intracellular K+ is adsorbed.
