pH measurements in non-aqueous and aqueous-organic solvents - definition of standard procedures.
pH standardisation procedures in non-aqueous and aqueous-organic solvents are discussed in the light of the newly prepared IUPAC recommendation on measurement of pH in dilute aqueous solutions. Both scientific and metrological aspects are considered, as required by the definitions of primary and secondary methods of measurements recently endorsed by BIPM (Bureau International de Poids et de Mesures, France).
