Early History of the Department of Chemisty of the Ohio State University

Author Institution: Department of Chemistry, Ohio State UniversitySidney Norton, appointed in 1873, was the first professor of chemistry at Ohio State, and for 20 years the only faculty member of the department. In these early years the annual student enrollment in chemistry was often less than 50. The growth of the department began in 1893 with the appointment of William McPherson as an assistant professor. By 1900, two more faculty members were added, and at the end of the first half century of its existence, there were 9 senior faculty members aided by a junior staff of about 40 assistants and graduate assistants. The undergraduate enrollment then totalled about 2,000 and the number of graduate students about 100

Composition of Ancient Peruvian Copper

Author Institution: Department of Chemistry, The Ohio State University, Columbus, 43210omplete quantitative analyses were made of samples of metal taken from fifteen Peruvian copper objects that came from various sites and ranged in date from the fourth to the fifteenth century A.D. Twelve of the samples were found to be composed of arsenical copper containing a wide variety of impurities. One was native copper and one other was apparently native copper modified by heat treatment. Only one sample contained enough tin to warrant classification as bronze. Some tentative general conclusions are advance

Wet Analysis of Gold-Silver Alloys of High Gold Content

Author Institution: Department of Chemistry, The Ohio State University, Columbus, OhioGold-silver alloys dissolve completely in mixtures of hydrochloric and nitric acids acids containing potassium chloride in high concentration. In an analytical procedure based on this observation, silver is separated and determined as the chloride, and gold as the metal after reduction with sulfite. Analyses of test alloys, synthetic mixtures, and ancient objects showed that this new procedure is practicable and that results of satisfactory accuracy can be obtained
