ABSTRACT:
Difficulties occur in finding an electrode which responds reliably to the concentration of some ions.
The concentration of a required ion in an electrolyte is measured by measuring the potential between first and second electrodes when the electrolyte is passed from the first electrode to the second electrode through a material which changes the concentration of another ion by an amount which depends on the concentration of the required ion. The first and second electrodes are reliable electrodes for measuring the concentration of the other ion.
