| Abstract | Accurate surface potentials measured by the radioactive electrode method are given for monolayers of sodium octadecyl sulphate spread on several aqueous sodium chloride solutions. In the temperature range 5–18°C, the magnitude of the surface potential increases with temperature for all salt solutions. This is interpreted as showing that increasing temperature disorients water dipoles more at the clean air/water interface than at the film-covered interface for long-chain sulphate over the temperature range studied. It is not possible from the data to determine uniquely the orientation of water molecules at the clean air/water interface, but it is almost certain that they are arranged with the oxygen atoms pointing towards the air phase.The general breakdown of the Gouy—Chapman model of the ionic double layer is confirmed at all temperatures. The Stern model as modified by van Voorst Vader and van den Tempel cannot explain the data. The classical Stern adsorption isotherm covers the results, giving Stern adsorption energies for the sodium ion which are negative (except possibly at very high charge densities) and vary significantly with salt concentration but do not vary with temperature and monolayer density in the area range 300 to 1200 Å2 molecule–1. |

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.
