This figure is reformulated to give a H+ concentration of 3.18 · 10−7 mol/l in pure H2O at 25°C. A new interpretation of the limiting equivalent conductances of HCl and KOH involving the collective motion of all ions in the bulk of the solution is given. Then a new mode of ...
In pure water [H + ] = [OH - ] = 1.0 x 10 -7 M and thus the amount of dissociation is extremely small. The dissociation constant for water can be written, K w = [H + ] [OH - ] / [H 2 O] = 1.0 x 10 -14 @25°C ...

Consequently, the normality of a reagent may be different, depending on the type of reactions involved in particular cases. Brown et al. (1991) explained: “For acid-base reactions, an equivalent of an acid is the quantity that supplies 1.0 mole of H+; an equivalent of a base is the ...
This explicitly holds for the pure advection case, while in the case of LSD presence the Moment Deriv-ing Function (MDF) is involved to ensure the moment collapse validity. Fur-thermore, the expected mass fraction (EMF) concept is applied in groundwater transport. In its origin, EMF is ...
摘要: PROBLEM TO BE SOLVED: To accurately measure the concentration of a sample liquid by eliminating the retention of bubble of a fermentation liquid, etc., in a piping through a specific operation of opening/closing mechanism in a liquid feeding mechanism....

Despite governing heat management in any realistic device, the microscopic mechanisms of heat transport in all-solid-state electrolytes are poorly known: existing calculations, all based on simplistic semi-empirical models, are unreliable for superionic conductors and largely overestimate their thermal condu...
To enable internal recycling of the leachant bleed and recover pure water, it is necessary to incorporate a concentration unit. In this paper different technologies for concentrating the mixed stream are compared. At a specified water recovery rate of 10 m3/h, the total costs for mechanical ...
