| Abstract | Copper dissolution in the aqueous systems DMSO-HX$_{solv}$ (solv = H$_{2}$O; X = Cl, Br) under the inert atmosphere and under aerobic conditions at different acid concentrations was studied by the resistometric method by measuring the resistance of a metal sample in the course of the reaction. The overall activity of the system decreases with a decrease in the concentration of the starting hydrohalic acid. The rate of copper dissolution in the extremum points also decreases. The process of the metallic copper dissolution in nonaqueous systems, such as DMSO-HCl$_{solv}$ (solv = MeCN, PhNO$_{2}$), was studied. In the latter systems, as opposed to aqueous systems, only one maximum in the plot of the copper dissolution rate versus the component ratio is observed. The change in the nature of the solvent in the donor-acceptor electron transport system DMSO-HCl$_{solv}$ (solv = H$_{2}$O, MeCN, PhNO$_{2}$) results in the change in the position of the maximum of the copper dissolution rate, as well as in the change in its value. The rate of copper dissolution in the above mentioned systems varies in the following series: H$_{2}$O < MeCN < PhNO$_{2}$. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
