Excerpt from Comparison of the Silver and Iodine Voltameters and the Determination of the Value of the Faraday
The details of each experiment made or attempted are given in Table 2. The experiment of June 6 which is designated as No. 1 we have omitted from the (summary of results contained in Table 3 since during the run iodine from the cathode was seen to have migrated up this limb and over into the anode side, coloring the liquid in the connecting V-tube quite distinctly.9 Before starting the experiment it had been suggested that the first run would be largely of a preliminary nature. Aside from this run the only silver voltameter measurements omitted in computing the results are those enclosed in brackets. One of 'them on July 22 deviates from'the mean by about four times the average deviation of the others and hence may be called a gross error. Two others, on July 30, were found to be alkaline at the close of the experiment which is suflicient reason to discard them as shown in previous investi gations.10 Owing to a miscalculation which resulted in much too little arsenious acid solution being weighed out for two of the voltameters of run No. 9, but one accurate analysis of the iodine formed in this experiment was obtained.
In the column of remarks the experiments designated as ab solute are those in which the current was maintained constant during the entire time of the run and measured in terms of a standard cell and resistance. In the comparative experiments this was not done.

Paperback. Condition: 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. Forgotten Books publishes hundreds of thousands of rare and classic books.
