Cxli. the Technique of Glass Electrode Measurements
IN the course of an investigation into the value of the glass electrode as a means of making continuous records of the hydrogen ion concentration of circulating blood, it was found, in the preliminary experiments in which estimations were made on single samples, that there were several sources of serious error. The difficulties encountered in devising a satisfactory apparatus for measuring glas...
متن کاملTHE KINETIC AND MECHANISM OF CRYSTALLIZATION OF MGGEO3 IN 65GEO2-15PBO-10MGF2-10MGO GLASS SYSTEM
In this study, the crystallization behavior of a 65GeO2-15PbO-10MgF2-10MgO glass (prepared by the conventional melt quenching technique) has been investigated. The microstructure and crystallization behaviors of this glass were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), non-isothermal differential thermal analysis (DTA) and Fourier transform infrared spectr...
متن کاملThe investigation of pyrocatechol electrochemical mechanism in presence of nitrite ion on platinum electrode
In this study, the electrochemical mechanism of catechol in presence and absence of nitrite ion, is investigated in phosphate buffer medium (pH=7) using platinum electrode through cyclic voltammetry method in various scan rates. Electrochemical oxidation of catechol showed how quinone has changed to o-benzoquinone and also how o-benzoquinone has reacted with nitrite ion and potential scan rate ...
متن کاملThe Validity of the Glass Electrode in Ammonium Chloride Buffers
It is shown that the glass electrode may be used without appreciable error to measure pH of ammonia or ammonium chloride buffers, but that corrections must be applied above pH 8.6 if sodium ions are present in the unknown solution. Corrections are given for values from pH 8.6 to 9.4. A slight further modification of form of glass electrode used by previous workers is described.
متن کاملDevelopment of the Glass Electrode and the pH Response
The glass electrode is the most commonly used device to access the pH of an aqueous solution. It attains highly accurate measurements via simple and well-established procedures. However, the reasons why the glass electrode potential scales with hydrogen ion concentration according to almost Nernstian potential values have been long-standing challenges to explain. Only in the past 50 years has a...
