WebCarbonic Acid Exchange Theory of Ion Uptake: According to this theory, the CO 2 released during respiration of root cells combines with water to form carbonic acid (H 2 CO 3 ). Carbonic acid dissociates into H + and an anion HCO 3 in soil solution. These H + ions may be exchanged for cations adsorbed on the clay particles.

Web2 feb. 2011 · Ion exchange is a rate-controlled process and the kinetics depends on the following five steps: Diffusion of the counterions through the bulk solution to the surface … WebFigure 1. Electrochemical cell for making a potentiometric measurement with an ISE. As indicated by their name, ion-selective electrodes possess a high degree of selectivity. The selectivity of the ISE is determined by the composition of the membrane. Ideally the membrane allows the uptake of only one specific ion into it. Ion exchange usually describes a process of purification of aqueous solutions using solid polymeric ion-exchange resin. More precisely, the term encompasses a large variety of processes where ions are exchanged between two electrolytes.
