TLDR
In this paper, it was shown that although the precise composition of the medium is a function of the hydrogen ion concentration (because of the protolytic nature of some of the ions in the media, e.g., sulphate and fluoride), the effect of such variations in the medium composition can be compensated for when defining the activity of hydrogen ion on an ionic medium standard state by defining the concentration of hydrogen ions as: [H] SWS =h(1 + β HSO 4 ST + β HF E T ) where βHSO4 and βHF are theAbout:

A comparison of the equilibrium constants for the dissociation of carbonic acid in seawater media
TL;DR: In this paper, the published experimental data of Hansson and Mehrbach et al. have been critically compared after adjustment to a common pH scale based upon total hydrogen ion concentration, and the results have been pooled to yield reliable equations that can be used to estimate pK1∗and pK2∗ for seawater media a salinities from 0 to 40 and at temperatures from 2 to 35°C.

Thermodynamics of the dissociation of boric acid in synthetic seawater from 273.15 to 318.15 K
TL;DR: In this paper, the stoichiometric (ionic medium) dissociation constant for boric acid in seawater media on the total hydrogen ion scale was calculated using the cell: Pt | H2(g,101.325 kPa) | borax in synthetic seawater | AgCl; Ag over the temperature range 273.15-318.15 K, and at five salinities from 5 to 45.E.m.f.

Platinized platinum electrodes
A.M. Feltham,Michael Spiro +1 more
TL;DR: The platinized platinum electrode is the most widely used type of electrode as mentioned in this paper, and it makes a regular appearance in conductance cells, forms the basis of the hydrogen reference electrode, and is unsurpassed as an electrocatalyst in fuel cells.
