Reference value standards and primary standards for pH measurements in organic solvents and water + organic solvent mixtures of moderate to high permittivities

Ref. value stds. (pHRVS) and primary stds. (pHS) for pH measurements detd. prior to 1985, the aggregation of new stds. freshly detd. in the light of IUPAC rules and procedures, and the compilation of recommended data were reexamd. The pHRVS data (the RVS material is the 0.05 m K H phthalate buffer) now available cover the following solvents and/or their mixts. with H2O: MeOH, EtOH, 2-PrOH, 1,4-dioxane, MeCN, DMSO, and D2O. The various pHS now available cover MeOH, EtOH, DMSO and D2O.
