An unusually high sensitivity of Pt-black pH electrode

Content Provider Springer Nature Link

Abstract The potentials of Pt-black electrode using a copper conducting wire instead of the salt bridge in acid and alkaline solutions without the use of H2 evolution reactions were measured. There were three nonlinear portions in the calibration curve. Unusually, the potential slopes at pH 3–5 and 8–10 indicated 200 mV and 70 mV per pH, respectively. Such high sensitivity for pH slope, more than 4 times of usual 59 mV per pH, may be credited to the special properties of the Pt-black surface. SEM (scanning electronical microscopy) was applied to characterize the surface of the Pt-black electrode. Its working mechanism is well explained in the theory of capacitance potentials rather than Nernst’s redox potentials.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
