Al t hough it is impossible to est ablish a t hermodynami c scale of hydrogen-io n a ctivi ty, Ug, t he N BS pH stand ards are assigned pH values that approa ch as closely as possible log U R in dilute b uffer solutions. In order to avoid t he un cer tainti es of t he liquid jun ction, electromotive-fo rce measurements of hydrogen-s ilver chloride cells lVithou t liquid jun ction were used to o...
متن کاملBuffer Solutions of Potassium Dihydrogen Phosphate and Sodium Succinate at 25 °C
A buffer mixture consist in g of eq ua l molali t ies (m ) of potass ium dihydrogen phospha te and sodium succina te is proposed as a useful reference poin t in the study of acid-base equilibria, b ridging t he present gap be tween pH 5.5 a nd pH 6.8. The p(aH'YCI) at 25 °0 has been determined by elect.romo tive-fo rce measuremen ts for fi ve buffer solu tions in which m varied from 0.005 to 0....
