Hydrated radius of ions
Web20 uur geleden · Ions have a finite radius and usually travel with a gang of several hydration water molecules attached with different degrees of adherence. Then, the radius of capture does not, and should not, coincide with the physical dimensions of the pore. WebWhere the ion with the larger hydrated radius is displaced by the smaller ion. So Li is displaced by sodium and Na is displaced by Ca Where Coulombic interactions dominate, the reverse is seen, and preference is given to the decreasing crystal radius. 4. Ion Exchange Equilibria: a) Exchange of like charged cations: A-Clay + B+ <---> B-clay + A+;
