Diffusion in Gases, Liquids and Electrolytes


Book Description

This volume contains data on diffusion in liquid mixtures. Diffusion processes are widespread phenomena in nature, of which mass diffusion is the most important one, in particular in liquids. The corresponding diffusion coefficients strongly depend on concentration, temperature, pressure and density. Contrary to the measurement of viscosity or heat transfer, where a few well developed experimental methods exist, we find a wide spectrum of different methods for measuring mass diffusion coefficients ranging from NMR spectroscopy, scattering, holography, interferometry, chromatography, diffusion through diaphragm and in capillary systems, and electroanalytical methods.After an introduction about the selection and normalization of data, in its first part this volume presents the most important measurement methods, followed by a second part on diffusion coefficient data depending on the various parameters.

Chemistry 2e


Book Description

Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition.

Diffusion


Book Description

This overview of diffusion and separation processes brings unsurpassed, engaging clarity to this complex topic. Diffusion is a key part of the undergraduate chemical engineering curriculum and at the core of understanding chemical purification and reaction engineering. This spontaneous mixing process is also central to our daily lives, with importance in phenomena as diverse as the dispersal of pollutants to digestion in the small intestine. For students, Diffusion goes from the basics of mass transfer and diffusion itself, with strong support through worked examples and a range of student questions. It also takes the reader right through to the cutting edge of our understanding, and the new examples in this third edition will appeal to professional scientists and engineers. Retaining the trademark enthusiastic style, the broad coverage now extends to biology and medicine.
