| buffer capacity definition chemistry: pH of the Skin: Issues and Challenges C. Surber, C. Abels, H. Maibach, 2018-08-21 The concept of expressing acidity as the negative logarithm of the hydrogen ion concentration was defined and termed pH in the beginning of the 20th century. The general usefulness of the pH concept for life science was recognized and later gained importance to analytical research. Reports on results of pH measurements from living skin established the term acid mantle - the skin's own protective shield that maintains a naturally acid pH. It is invisible to the eye but crucial to the overall wellbeing of skin. Chronic alkalization can throw this acid mantle out of balance, leading to inflammation, dermatitis, and atopic skin diseases. It is therefore no surprise, that skin pH shifts have been observed in various skin pathologies. It is also obvious that the pH in topically applied preparations may play an important role. Optimal pH and buffer capacity within topical preparations not only support stability of active ingredients and auxiliary materials, but may also increase absorption of the non-ionized species of an acidic or a basic active ingredient. They may even open up opportunities to modify and correct skin pH and hence accelerate barrier recovery and maintain or enhance barrier integrity. Further efforts are needed to standardize and improve pH measurements in biological media or pharmaceutical/cosmetic vehicles to increase and ensure quality, comparability, and relevance of research data. In this volume, we present a unique collection of papers that address past, present and future issues of the pH of healthy and diseased skin. It is hoped that this collection will foster future efforts in clinical and experimental skin research. |

| buffer capacity definition chemistry: Determination of PH Roger Gordon Bates, 1964 In portraying the rise and fall, in eighteenth century Ireland and England, of Barry Lyndon - an adventurer-gambler, a cad and a romantic idealist - Kubrick departs from Thackeray's picaresque novel in scope and tone. The first person narrator of the novel gives way in the film to the third person who assumes a good deal of the storytelling function, adding to the sense of detachment and abstraction typical of Kubrick. The way that this film polarised the critics suggests that it may hold a key to his oeuvre. Enervating pictorialism or a stately meditation upon the trappings of cultural ritual that we call civilisation? The painterly tableaux suggest the 'otherness' of a past era - a world as alien as that of 2001 - in a way matched by few other period films. |

| buffer capacity definition chemistry: Ionic Equilibrium James N. Butler, 1998-04-13 A celebrated classic in the field updated and expanded to includethe latest computerized calculation techniques In 1964, James N. Butler published a book in which he presentedsome simple graphical methods of performing acid-base, solubility,and complex formation equilibrium calculations. Today, both thebook and these methods have become standard for generations ofstudents and professionals in fields ranging from environmentalscience to analytical chemistry. Named a Citation Classic by theScience Citation Index in 1990, the book, Ionic Equilibrium,continues to be one of the most widely used texts on the subject.So why tamper with near-perfection by attempting a revision of thatclassic? The reason is simple-- the recent rapid development andwide availability of personal computers. In the revised Ionic Equilibrium, Dr. Butler updates his 1964 workby abandoning the slide rule and graph paper for the PCspreadsheet. He also expands the original coverage with extensivematerial on basic principles and recent research. The first part of Ionic Equilibrium is devoted to the fundamentalsof acid-base, solubility, and complex formation equilibria. In thesecond part, the author discusses oxidation-reduction equilibria,develops the principles of carbon dioxide equilibria, presents casestudies demonstrating the ways in which carbon dioxide equilibriaare used in physiology and oceanography, and explores thepossibility of a pH scale for brines. The concluding chapter,written by David R. Cogley, gives examples of general computerprograms that are capable of performing equilibrium calculations onsystems of many components. Replete with real-world examples, details of importantcalculations, and practical problems, Ionic Equilibrium is an idealcourse text for students of environmental chemistry, engineering,or health; analytical chemistry; oceanography; geochemistry;biochemistry; physical chemistry; and clinical chemistry. It isalso a valuable working resource for professionals in those fieldsas well as industrial chemists involved with solution chemistry. |

| buffer capacity definition chemistry: Misconceptions in Chemistry Hans-Dieter Barke, Al Hazari, Sileshi Yitbarek, 2008-11-18 Over the last decades several researchers discovered that children, pupils and even young adults develop their own understanding of how nature really works. These pre-concepts concerning combustion, gases or conservation of mass are brought into lectures and teachers have to diagnose and to reflect on them for better instruction. In addition, there are ‘school-made misconceptions’ concerning equilibrium, acid-base or redox reactions which originate from inappropriate curriculum and instruction materials. The primary goal of this monograph is to help teachers at universities, colleges and schools to diagnose and ‘cure’ the pre-concepts. In case of the school-made misconceptions it will help to prevent them from the very beginning through reflective teaching. The volume includes detailed descriptions of class-room experiments and structural models to cure and to prevent these misconceptions. |
| buffer capacity definition chemistry: The Determination of Ionization Constants Adrien Albert, 2012-12-06 This practical manual is devised for organic chemists and biochemists who, in the course of their researches and without previous experience, need to determine an ionization constant. We are gratified that earlier editions were much used for this purpose and that they also proved adequate for the in service training of technicians and technical officers to provide a Department with a pK service. The features of previous editions that gave this wide appeal have been retained, but the subject matter has been revised, extended, and brought up to date. We present two new chapters, one of which describes the determination of the stability constants of the complexes which organic ligands form with metal cations. The other describes the use of more recently introduced techniques for the determination of ionization constants, such as Raman and nuclear magnetic resonance spectroscopy, thermometric titrations, and paper electro phoresis. Chapter 1 gives enhanced help in choosing between alternative methods for determining ionization constants. The two chapters on potentiometric methods have been extensively revised in the light of newer understanding of electrode processes and of the present state of the art in instrumen tation. |
| buffer capacity definition chemistry: Buffers for pH and Metal Ion Control D. Perrin, 2012-12-06 This book is intended as a practical manual for chemists, biologists and others whose work requires the use of pH or metal-ion buffers. Much information on buffers is scattered throughout the literature and it has been our endeavour to select data and instructions likely to be helpful in the choice of suitable buffer substances and for the preparation of appropriate solutions. For details of pH measurement and the preparation of standard acid and alkali solutions the reader is referred to a companion volume, A. Albert and E. P. Serjeant's The Determination of Ionization Constants (1971). Although the aims of the book are essentially practical, it also deals in some detail with those theoretical aspects considered most helpful to an understanding of buffer applications. We have cast our net widely to include pH buffers for particular purposes and for measurements in non-aqueous and mixed solvent systems. In recent years there has been a significant expansion in the range of available buffers, particularly for biological studies, largely in conse quence of the development of many zwiUerionic buffers by Good et al. (1966). These are described in Chapter 3. |

| buffer capacity definition chemistry: Environmental Neurotoxicology National Research Council, Division on Earth and Life Studies, Commission on Life Sciences, Board on Environmental Studies and Toxicology, Committee on Neurotoxicology and Models for Assessing Risk, 1992-02-01 Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students. |
