Reference value standards and primary standards for pH measurements in D2O and aqueous-organic solvent mixtures: new accessions and assessments / P.R. Mussini, T. Mussini, S. Rondinini. - In: PURE AND APPLIED CHEMISTRY. - ISSN 0033-4545. - 69:5(1997 May), pp. 1007-1014. [10.1351/pac199769051007]
Abstract:
Recommended Reference Value Standards based on the potassium hydrogenphthalate buffer at various temperatures are reported for pH measurements in various binary solvent mixtures of water with eight organic solvents: methanol, ethanol, 2-propanol, 1,2-ethanediol, 2-methoxyethanol (''methylcellosolve'), acetonitrile, 1,4-dioxane, and dimethyl sulfoxide, together with Reference Value Standards based on the potassium deuterium phthalate buffer for pD measurements in D2O. In addition are reported Primary Standards for pH based on numerous buffers in various binary solvent mixtures of water with methanol, ethanol and dimethyl sulfoxide, together with Primary Standards for pD in D2O based on the citrate, phosphate and carbonate buffers.
