State-of-the-Art pH Electrode Quality Control for Measurements of Acidic, Low Ionic Strength Waters.

Stapanian, Martin A.; Metcalf, Richard C.

Journal of Chemical Education, v67 n7 p623-26 Jul 1990

Described is the derivation of the relationship between the pH measurement error and the resulting percentage error in hydrogen ion concentration including the use of variable activity coefficients. The relative influence of the ionic strength of the solution on the percentage error is shown. (CW)
