The relation of hydrogen-ion concentration to the speed of inversion of sucrose

Bartlett, Frederick Sheldon 01 January 1926 (has links) (PDF)
In general, the velocity of inversion of sucrose ie a function of several variables; namely, the temperature, the viscosity, and the concentrations of hydrogen ions, undissociated acid, sucrose, added salts, and non-electrolytes. It can readily be seen, then, that this reaction offers a broad field for research with decidedly varied and diversified lines of attack.

Liquid junction potentials at mixed electrolyte salt bridges

Finkelstein, Noel Phillip January 1957 (has links)
The potentiometric method is one of the most exact techniques of electrochemistry. Its use is widespread in both routine measurements, such as pH determination, and in applications which demand the highest accuracy. Perhaps its severest limitation is the error due to liquid junction potentials. Although this has been the subject of much study, and although various means of combating it have been proposed, it has defied all attempts at a satisfactory solution. Indeed, so serious is the position that it has become the accepted practice in the more accurate fields to abandon altogether the use of potentiometric techniques in favour of others, usually less convenient and otherwise less accurate, when the presence of liquid junctions cannot be avoided.

ELECTRON IMPACT DISSOCIATIVE IONIZATION OF HYDROGEN, WATER, AND HYDROGEN SULFIDE.

CORDARO, RICHARD BRIAN. January 1985 (has links)
The dissociative ionization by electron impact of H₂, H₂O, and H₂S was investigated between the electron impact energies of 20 and 45 eV. Protons were the detected fragments, and a time-of-flight method was used to measure the proton kinetic energies. By also measuring the thresholds for the production of discrete energy groups of protons, it was possible to determine the dissociation limits and kinetic energy distributions for individual electronic states. It was found that autoionizing states that lead to dissociation were the major contributors of proton fragments for all of the molecules investigated. Some of the measurements are tabulated in the following table.
