Abstract
Abstract This work presents an in‐depth study of the interrelation between the junction potential E J and the activity of individual ions. The need to correct for the sign of the junction potential employed in previous publications is used to confirm that the calibration of the ion‐selective electrodes largely cancels errors in the estimation of E J . Revised values of the activity coefficients of individual ions are presented for all systems previously measured. A rederivation of Henderson equation is used to clarify the interpretation of its terms for asymmetric electrolytes. A new analytical equation to calculate E J is derived and tested. This equation corrects for the nonideality of solutions and for the concentration dependence of the conductivity. The correction for nonideality is only necessary for the ions present in both the sample and the reference electrode solutions. The new equation represents a major improvement over the Henderson equation for E J calculations. © 2004 American Institute of Chemical Engineers AIChE J, 50: 445–462, 2004

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
