The reversible potential, Er (equilibrium potential, namely theoretical voltage of electrolysis) is given by following equation: Er=E0−RT2FlnPP0 where E0 is the standard equilibrium potential, R is the gas constant, T is the absolute temperature, P0 and P are the vapor pressure of pure wat...
Provide the specific form of the equation (that allows one to calculate the pH of a buffer solution) including each chemical species, that will allow one to calculate the pH of a bicarbonate buffered solution. What happens when gluten is not broken down correctly by the digestive system?
Using the Nernst-Planck equation, a useful expression for the potential drop in the presence of diffusion, migration, and advection is derived. A quasi-stationary, one-dimensional model is used to successfully describe the transient dynamics. Electro-osmotic flow-driven cross-over of dissolved ...
Membrane-based alkaline water electrolyser is promising for cost-effective green hydrogen production. One of its key technological obstacles is the development of active catalyst-materials for alkaline hydrogen-evolution-reaction (HER). Here, we show that the activity of platinum towards alkaline HER ...
spectra were recorded and analyzed with MestReNova (Mestrelab research, version 5.2.5–4119). The resulting sigmoidal curve was subjected to nonlinear curve fitting using Prism® (GraphPad, version 5.0b and 5.0f). The dissociation constantpKawas calculated Henderson-Hasselback equation (Eqs.(1–4...

The equilibrium potential represents the minimum energy required to drive the water splitting reaction [35]:(2–3)Veq=−ΔG2F,where ΔG is the Gibbs free energy (kJ/mol) [34]. According to the Nernst equation, the equilibrium potential can be expressed as [36]:(2–4)Veq=V0+(T−...
In many texts the sodium and alumina ions produced in equation (13.10) are written as NaAlO2·xH2O, and some workers have claimed the occurrence of this compound as a solid phase in concretes subject to alkaline hydrolysis.157,158 The compound Na2[Al2O3(OH)2]·1.5H2O(NAH2.5) can only ...
(E) were converted to the reversible hydrogen electrode (RHE) based on the following equation: ERHE = EHg/HgO + 0.059 pH + E0Hg/HgO. The potential of reference electrode and the pH value of the used electrolyte were examined before the electrochemical measurement (...
