Abstract
VARIOUS forms of carbon have been considered as possible indicator electrodes for use in locating end points in acid–base titrations; these forms have included graphite1, vitreous or glassy carbon2 and pyrolytic graphite3. Microelectrodes can be used in titrations of small volumes, such as those found in biological cells4, and certain forms of carbon such as glassy carbon, are exceptionally resistant to oral and tissue fluids5. We have examined the electrical potential response of a single carbon fibre to pH changes in aqueous electrolyte solutions.
