The Practice of Chemistry Education (Paper)
CHEMISTRY EDUCATION: THE PRACTICE OF CHEMISTRY EDUCATION RESEARCH AND PRACTICE (PAPER) 2004, Vol. 5, No. 1, pp. 69-87 Concept teaching and learning/ History and philosophy of science (HPS) Juan QUÍLEZ IES José Ballester, Departamento de Física y Química, Valencia (Spain) A HISTORICAL APPROACH TO THE DEVELOPMENT OF CHEMICAL EQUILIBRIUM THROUGH THE EVOLUTION OF THE AFFINITY CONCEPT: SOME EDUCATIONAL SUGGESTIONS Received 20 September 2003; revised 11 February 2004; in final form/accepted 20 February 2004 ABSTRACT: Three basic ideas should be considered when teaching and learning chemical equilibrium: incomplete reaction, reversibility and dynamics. In this study, we concentrate on how these three ideas have eventually defined the chemical equilibrium concept. To this end, we analyse the contexts of scientific inquiry that have allowed the growth of chemical equilibrium from the first ideas of chemical affinity. At the beginning of the 18th century, chemists began the construction of different affinity tables, based on the concept of elective affinities. Berthollet reworked this idea, considering that the amount of the substances involved in a reaction was a key factor accounting for the chemical forces. Guldberg and Waage attempted to measure those forces, formulating the first affinity mathematical equations. Finally, the first ideas providing a molecular interpretation of the macroscopic properties of equilibrium reactions were presented. The historical approach of the first key ideas may serve as a basis for an appropriate sequencing of -

The History of the Concept of Element, with Particular Reference to Humphry Davy
The Physical Sciences Initiative The history of the concept of element, with particular reference to Humphry Davy One of the problems highlighted when the recently implemented chemistry syllabus was being developed was the difficulty caused by starting the teaching of the course with atoms. The new syllabus offers a possible alternative teaching order that starts at the macroscopic level, and deals with elements. If this is done, the history of the idea of elements is dealt with at a very early stage. The concept of element originated with the ancient Greeks, notably Empedocles, who around 450 BC defined elements as the basic building blocks from which all other materials are made. He stated that there were four elements: earth, air, fire and water. Substances were said to change when elements break apart and recombine under the action of the forces of strife and love. Little progress was made in this area until the seventeenth century AD. The fruitless attempts of the alchemists to change base metals such as lead into gold and to find the “elixir of life” held back progress, although much chemical knowledge and expertise was gained. In 1661, 1 The Physical Sciences Initiative The Physical Sciences Initiative Robert Boyle defined an element as a substance that cannot be broken down into simpler materials. He cast doubt on the Greek elements, and provided a criterion for showing that a material was not an element. Robert Boyle Many elements were discovered during the next 100 years, but progress was delayed by the phlogiston hypothesis. According to this hypothesis, when a substance was burned it lost a substance called phlogiston to the air. -

But this col- umn’s book is by someone you probably have not heard of unless you are quite familiar with 17th Century science. This author is Nicolas Lemery, born in Rouen in November 1644 or 1645, died in Paris in 1715. His father was a lawyer to the Normandy Parliament and a Protestant. Nicolas was apprenticed to a pharmacist who was a relative, but he moved to Paris in 1666 to work at the Jardin du Roi, the Royal Botanic Garden that included science laboratories, and sponsored science lectures. (Lavoisier, a century later, learned much of his chemistry at this institution.) Lemery’s mentor was Glaser but they did not get on and he moved to Montpellier where he set up a laboratory, made and sold chemicals and pharma- ceuticals, and began to give lectures on chemistry illustrated by experiments. These lectures established his fame and attracted many (paying) attendees including women and foreign students. Lemery’s Protestant faith led to conflicts with the Catholic authorities and from 1683-84 he visited Protestant England. Returning to France he earned an M.D. -

Special attention is given to his work in life science which he had done in the second half of his scientific career and was the base of the development of nuclear medicine. Keywords: George de Hevesy; Radionuclides; Nuclear Medicine Introduction George de Hevesy has founded Radioanalytical Chemistry and Nuclear Medicine, discovered the element hafnium and first separated stable isotopes. He was an inventor in many disciplines and his interest was not only focused on the development and refinement of methods, but also on the structure of matter and its changes: atoms, molecules, cells, organs, plants, animals, men and cosmic objects. He was working under complicated political situation in Europe in the 20th century. During his stay in Germany, Austria, Hungary, Switzerland, Denmark, and Sweden he wrote a lot papers in German. In 1962 he edited a large part of his articles in a collection where German papers are translated in English [1]. -

Queen Christina's Esoteric Interests As a Background to Her
SUSANNA ÅKERMAN Queen Christina’s Esoteric Interests as a Background to Her Platonic Academies n 1681 the blind quietist, Francois Malaval, stated that Queen Christina of Sweden late in life had ‘given up’ [Hermes] Trismegistos and the IPlatonists, in favour of the Church fathers. The statement does not ex- plain what role the Church fathers were to play in her last years, but it does show that Christina really had been interested in the rather elitist and esoteric doctrine of Hermetic Platonic Christianity. In this paper I shall look at her library to show the depth of this Hermetic involvement. Her interest serves as a background to her life as ex-queen in Italy after her famous abdication from the Swedish throne in 1654, when she was 27 years old. Christina styled herself as the Convert of the Age, and she set up court in Rome where she held a series of scientific and cultural acad- emies in her palace. Her Accademia Reale was staged briefly in the Palazzo Farnese in her first year in Rome, 1656, but was revived in 1674 and was held for a number of years in her own Palazzo Riario.1 Also, Giovanni Ciampini’s Accademia dell’Esperienze, also called Ac cademia Fisico-mathematico, gathered there for their first founding meeting in 1677. Furthermore, she was protectress of the Accademia degli Stravaganti in Collegio Clementina from 1678 and in Orvieto for the Accademia dei Misti. (Christina 1966: 377, cited below as NMU.) Her inspirational presence and resources were valued by many liter- ary figures. After her death in 1689, she was chosen to be a symbolic figurehead, Basilissa (Greek for Empress), by the poets that formed the Accademia dell’Arcadia (D’Onofrio 1976). -

Wilhelm Ostwald – the Scientist
ARTICLE-IN-A-BOX Wilhelm Ostwald – The Scientist Friedrich Wilhelm Ostwald was born on September 2, 1853 at Riga, Latvia, Russia to Gottfried Ostwald, a master cooper and Elisabeth Leuckel. He was the second son to his parents who both were descended from German immigrants. He had his early education at Riga. His subsequent education was at the University of Dorpat (now Tartu, Estonia) where he enrolled in 1872. At the university he studied chemistry under the tutelage of Carl ErnstHeinrich Schmidt (1822– 1894) who again was a pupil of Justus von Liebig. Besides Schmidt, Johannes Lemberg (1842– 1902) and Arthur von Oettingen (1836–1920) who were his teachers in physical chemistry were also principal influences. It was in 1877 that he defended his thesis ‘Volumchemische Studien über Affinität’. Subsequently he taught as Privatdozent for a couple of years. During this period, his personal life saw some changes as well. He wedded Helene von Reyher (1854–1946) in 1880. With Helene, he had three sons, and two daughters. Amongst his children, Wolfgang went on to become a famous colloid chemist. On the strength of recommendation from Dorpat, Ostwald was appointed as a Professor at Riga Polytechnicum in 1882. He worked on multiple applications of the law of mass action. He also conducted measurements in chemical reaction kinetics as well as conductivity of solutions. To this end, the pyknometer was developed which was used to determine the density of liquids. He also had a thermostat built and both of these were named after him. He was prolific in his teaching and research which helped establish a school of science at the university.
