The functional groups that are responsible for the ion-exchange property of cation and anion exchange resins, respectively, are :
Solution
Cation exchange resins contain large organic
a molecule with –SO<sub>3</sub>H group.<br><br>
In the cation exchange process H<sup>+</sup> exchanges for Na<sup>+</sup>,
Ca<sup>2+</sup>, Mg<sup>2+</sup> and other cations present in water.<br><br>
While anion exchange resins contain –NH<sub>2</sub> in form
of –NH<sub>3</sub><sup>+</sup> OH<sup>–</sup> where OH<sup>–</sup> exchanges for anions like
Cl<sup>–</sup>, HCO<sub>3</sub><sup>–</sup>, SO<sub>4</sub>
<sup>2–</sup>, etc.
