Excerpt from Journal of the Chemical Society, 1906, Vol. 89: Transactions, Part IIDuring the development of a more accurate method (denison and Steele, P/iil. Trans, 1906, 205, A, 449) than that previously adopted for the direct measurement of ionic velocities, we have repeatedly noticed that when certain salts were employed as indicators there was a constant retardation of the margin under observation. It had been previously pointed out (steele, Phil. Trans, 1901, 198, A, 105) that one of the necessary conditions for a constant margin-velocity was that the indicator should not undergo hydrolysis, and a number of cases of retardation referred to above have been traced to the fact that the indicators in question were somewhat hydro lysed. It occurred to us that the retardation might be capable of quantitative measurement, and might serve as a means of determining, at least approximately, the extent of hydrolysis of the indicator. Our anticipations have been more than realised, as we have found the above principle to be capable of development to an accurate method of measuring hydrolysis which can be carried out with considerable rapidity and in solutions of widely varying con centration.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
