Practical measurements of pH in the marine environment have as their usual objective the assessment of acid-base speciation. In order for accurate results to be obtained, the three pH scales in common use must be coupled each with its corresponding acid-base dissociation constant. For consistency in marine studies, it is desirable that a single procedure be selected and used by all marine scientists.

This document deals with definitions, procedures and terminology for the quantity pH which is of wide interest for chemists, biologists and engineers. It is the result of discussions since 1977 within IUPAC and related discussions in other international bodies. It constitutes in the definition of pH scales a compromise which recognises the advantages of both the previously endorsed multistandard approach and that based on the definition of a single standard with associated operational standards.
We have investigated the variations in the potentials of sodium-selective glass-membrane electrodes in various concentrations of albumin. These protein solutions serve as a simple model for measurements of electrolytes in whole blood, plasma, or serum with such an electrode. The results indicate that albumin-sodium binding and variations in liquid-junction potentials are of negligible importance. Mostly, the effect of albumin on the sodium glass-electrode potential is attributable to variations in the activity of sodium, determined by the water content of the solutions. We have calculated apparent fractional protein volumes in albumin solutions from measurements of sodium glass-electrode potential and find they compare well with the classical McLean-Hastings formulation. Our results indicate the need to correct experimentally determined potentiometric electrolyte concentrations for protein volumes.

I. INTRODUCTION AND SCOPE The term 'ion-selective electrodes' is applied to a range of membrane electrodes which respond selectively toward one (or several) ionic species in the presence of others. The less-preferred term 'ion-specific' is not favored1 because these electrodes are rarely specific in their response to one ionic species over others, although this is a desirable property sought by the designer of new electrodes. The description membrane is used here in its broadest sense to denote a thin section of electrically conducting material separating two solutions and across which a potential develops. Often the term membrane has associated with it the notion of permeability to a species present in the flanking solutions. However, although this is undoubtedly true with certain porous biological and synthetic membranes, the actual mechanism of electrical conduction in general varies with the type of membrane material; indeed it may change within it.
