The compact thermodynamic approach to the systems containing calcium, magnesium, and carbonate species is referred to dissolution of dolomite, as an example of nonequilibrium ternary salt when introduced into aqueous media. The study of dolomite is based on all attainable physicochemical knowledge, involved in expressions for equilibrium...

Nowadays, food industries are concerned about satisfying legal requirements related to waste policy and environmental protection. In addition, they take steps to ensure food safety and quality products that have high nutritional properties. Anthocyanins are considered high addedvalue compounds due to their sensory qualities, colors, and...

En este trabajo se aborda el estudio del proceso de implantación del Sistema de Transferencia de Créditos Europeos (ECTS), unidad fundamental del Espacio Europeo de Educación Superior (EEES), en la Titulación actual de Farmacia de la Universidad de Sevilla. Tras unas consideraciones previas, se establecen los objetivos fundamentales del...

A bilogarithmic hyperbolic cosine method for the evaluation of overlapping formation constants at varying (or fixed) ionic strength is devised in this paper and applied to data reported in the analytical literature, i.e. succinic acid system, Cu(II)-glycine system and Ag(I)-aminobutan -1-ol system. The method is based on the linearization of...

En este trabajo se incide en el tema de la adulteración de los alimentos en Gran Bretaña durante el siglo XVIII en la etapa previa a la creación de la "Society of Public Analysts". En la lucha contra el fraude alimentario y los aspectos que ello conlleva (analíticos, legales, educativos) radica el origen de esta asociación, que sigue a la...

En la primera parte de esta contribución se han abordado la condiciones de contorno del nuevo método de blanqueo que idea Berthollet tras el descubrimiento del cloro (ácido muriático oxigenado) por Scheele. Esta segunda se centra en lo concerniente a la relevante figura del farmacéutico Descroizilles, y a las variadas facetas a las que se...

Some aspects of the connexion between chemistry and pharmacy are considered under the framework of the Royal Academy of Sciences of France (1666-1793). Pharmacists have been active elements in the constitution, operation and management of important scientific societies. The contribution of apothecary and chemically formed doctors to chemistry...

The antioxidant activity of anthocyanins in food is well known. Numerous antioxidant assays have been proposed to measure the capacity of anthocyanins to prevent the oxidation process that naturally occurs. Different solvents, temperatures, and pH levels are applied in each assay, and these factors should be taken into account in order to...

Los halógenos han constituido un campo de batalla particular de los investigadores farmacéuticos. Cloro, bromo y iodo, se encuentran estrechamente relacionados con los métodos volumétricos, en sus comienzos. El color azul del complejo iodo-almidón que sirve como indicador para la detección de cantidades traza de iodo, es observado por Colin y...

The general formulation of dynamic buffer capacity for polyprotic acids and bases (and polyprotic acid and base salts) has been derived. Polyprotic acids show buffer capacity over a broad range of pH values, according to their successive protonation constants. Polyprotic acids with equidistant pki values behave as universal buffers. The paper...
