The 'traditional' approach developed from the pioneering work of Henderson and Hasselbalch and is still the most widely used in clinical practice. There are a number of problems identified with this approach, however. The 'modern' approach derives from Stewart's work in physical chemistry. In ...

and spectra of Lewis acid-base adducts or donor-acceptor complexes, nor is it truly a textbook. Rather it is a cross between a retrospective essay and a current review. Its purpose is to explore the potential of the Lewis acid-base concepts as a systematizing tool in chemistry, and to d...
Learn how to determine the conjugate acid or base, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
It’s the little touches that make a project, and a nice nameplate can really tie a retro build together. Such badges are easy enough to make with a CNC machine, but if you don’t have access to machine tools you can put chemistry to work for you withthese acid-etched brass nameplate...
The failure of this approach was in the inability of the simplified continuum model to predict the acid base chemistry of the more complex liquid. More realistic simulations predict that the distribution of species in 1-BEIPADIP-2-BOL is 50:50 of the neutral acid, reducing the degree of ...

This paper describes the synthesis and characterisation of an isatin Schiff base, namely 2-(2-oxoindolin-3-ylidene) hydrazinecarbothioamide (OHB). The chemical structure of OHB was elucidated through proton-nuclear magnetic resonance (1H-NMR), carbon-nuc
Melamine is a weak base, which can form well-defined, thermally stable salts, with both organic and inorganic acids. The salts, having been found to possess flame retardant characteristics, and for that reason, commonly used in practice for improving polymer fire behavior, are melamine cyanurate,...
