Paperback. Condizione: New. Print on Demand. This book investigates the faraday, a constant used to convert electrical charge into the amount of chemical change produced by that charge. The author presents a detailed description of the methods used to measure the faraday, as well as an analysis of the sources of error in these measurements. These issues are investigated using two separate apparatuses - silver and iodine voltameters. This work builds on previous research on the iodine voltameter and benefits from advances in techniques and technology to achieve more accurate results. Through these experiments, the author presents a revised estimate for the faraday constant with an uncertainty of less than 0.1%, a significant improvement on previous estimates. These findings have implications for electrochemistry and the precise measurement of electric charge.

Paperback. Condizione: New. Print on Demand. This book explores the inaccuracies inherent in electrochemical measurements of silver voltameters, a tool used to measure the quantity of electricity that has passed through a circuit. The author discovered that previous observers had failed to account for the alloying of silver and platinum that occurs when the deposits are heated to remove inclusions. This alloying can lead to significant errors in the measurements, as the presence of platinum black or platinum gray can affect the mass of silver deposited. The author found that the inclusions in pure electrolyte deposits were only about 0.0004 percent, significantly lower than previously reported. This book provides a valuable examination of the limitations and complexities of electrochemical measurements, highlighting the importance of careful experimentation and accurate interpretation of results.

Paperback. Condizione: New. Print on Demand. This book represents the final investigations into the electrochemical equivalent of silver as determined by the voltameter. The voltameter is an apparatus used to define the ampere and the volt. The series of experiments described had the goal of improving the accuracy of the voltameter to six significant figures. The authors conducted experiments to determine the impact of trace impurities in the electrolyte as well as variations in other conditions. They then derived formulas to correct for the effects of acid concentration and reported their results on the voltage of the Weston normal cell and the resistances used to measure the voltage. This book serves as a valuable resource for understanding the historical development of electrical standards and provides insights into the challenges and complexities of precision measurements in electrochemistry.

Paperback. Condizione: New. Print on Demand. This book begins by examining the history of the silver voltameter and summarizing the contributions of previous researchers, finding that the deposited silver often varied considerably from the predicted quantity. The author set out to eliminate the uncertainties and improve the precision of this measurement, examining the effects of pressure, temperature, used solutions, electrode sizes, and comparing the commonly used porous cup form with a new lter paper design. They found that the porous cup design had the advantage, as it protected the cathode from secondary oxidation products formed at the anode. The work presented here increased the precision of the voltameter as an instrument and helped pave the way for its adoption as an international electrical standard.

Paperback. Condizione: New. Print on Demand. This book presents a detailed chemical analysis of the silver voltameter, an apparatus used to measure electrical current by the mass of silver deposited on one of its electrodes. The author begins by discussing the qualitative and quantitative experiments that led to the voltameter's development, providing historical context for the instrument's invention and refinement. They then delve into the chemistry of the filter paper used in the voltameter, demonstrating how impurities in the paper can affect the accuracy of the measurements. Through a series of experiments, the author isolates the specific chemical reactions responsible for these inaccuracies and identifies the products formed during the electrolysis process. These insights are significant because they not only improve the precision of the silver voltameter but also contribute to a deeper understanding of the chemical reactions involved in electrolysis, which has applications in various fields of science and industry.

Paperback. Condizione: New. Print on Demand. This book reports on a series of experiments conducted by the U.S. Railroad Administration, Bureau of Standards, and various foundries to investigate the quality of iron used for locomotive cylinder parts. The book reviews relevant literature and previous specifications. It contains the results of mechanical, chemical, and microscopical tests performed on a number of packing rings, arbitration bars, chill-test specimens, and other samples. The tests were conducted to evaluate the influence of chemical composition, manufacturing process, and storage conditions on the strength and wear resistance of cast iron. The author discusses the relationship between laboratory test results and service performance and concludes that the air-furnace process produces iron with better mechanical properties and lower sulfur content than the cupola process. The book provides valuable insights for engineers and manufacturers seeking to improve the quality and performance of cast iron components in locomotive engines.
