Consideration of relative oxidizing/reducing strength is greatly facilitated when this topic is presented in terms of transfer of one or more electrons between members of a conjugate redox pair. (DF)

Two topics are discussed: (1) Stomach Upset Caused by Aspirin, illustrating principles of acid-base equilibrium and solubility; (2) Physical Chemistry of the Drinking Duck, illustrating principles of phase equilibria and thermodynamics. (DF)

It is shown that students have no difficulty scaling small diameter standard wall tubing if an explanatory sequence is incorporated into the experimental writeup. (DF)

A plea is made to prepare present day students for their future roles in the field. (DF)

A course is presented with emphasis on physical chemistry, problem solving, and instrumental methods of analysis, with an attempt to relate chemical principles with engineering concepts. (DF)

A course is developed for students who may not major in chemistry or science in college, and may not even go to college. Presentation is based on key topics with the inclusion of objectives. (DF)

Research has progressed from three major directions--biological, chemical, and non-enzymatic. Hopefully all three will converge and will explain not only the process, but also introduce new means for modifying the molecule to meet the nutritional needs of man in areas now incapable of self support without fixed nitrogen. (DF)

It is shown that the phenomenon of synergism has been known and used in chemistry for centuries and future outlooks for its application are favorable. Examples illustrating its use are included. (DF)

A translation into English of a dissertation of historical interest containing possibly the first equivalent weights for metals ever reported. (DF)

An historical investigation into the theory of valency as developed in the course of the second half of the 19th Century. Opposing views on one aspect of valency are examined and contrasted. (DF)

It is suggested that competitive examinations in chemistry should be produced which will be given annually over the nation at the advanced undergraduate level. (DF)
