Question

Quizplus · Accepted Answer

Hydrogen permeation rates are minimal at neutral pH (7) because the concentration of hydrogen ions is balanced, reducing the driving force for diffusion. At both higher and lower pH levels, the imbalance in hydrogen ion concentration increases permeation rates.
