Ionic strength and pka
Web17 aug. 2024 · This page explains the terms strong and weak as applied to acids. As a part of this it defines and explains what is meant by pH, K a and pK a.. It is important that you … Weboverall ionic strength is due predominantly to the particles or macroions and the compensating counterions in solution, whereas the concentration of any additional ions is negligible. For colloidal dispersions this assumption is again legitimate if the specific surface area carrying the colloidal charge is large.
