    systems‚ the mixed-bed ion-exchange stage was preceded by separate cation and anion exchange vessels. As applications became more demanding‚ it was clear that chemically regenerated ion exchange systems had limitations. ” “Ion-exchange resins are typically styrene and divinylbenzene copolymers cross-linked to form beads between 0.03 and 1.0 mm. The beads are converted into cation-exchange resins through a sulfonation process‚ or anion-exchange resins through chloromethylation.” “EDI removes ions from

    Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms. Translation: -Ionic bonding happens between a metal and a non-metal (east coast and west coast) -One atom completely donates its valence electrons to another atom -Metals become CATIONS (positive charge/oxidation state); Non-metals become ANIONS (negative charge/oxidation state) Example: Na + Cl → Na+Cl- or Mg

    is. Electrolytes or any ionic compound conduct electricity and nonelectrolytes do not conduct electricity. An Ionic compound is formed from the electrical attraction between anions and cations‚ typically a metal with a non-metal‚ except hydrogen. When an ionic compound forms‚ the anion transfers an electron to the cation which creates an electrostatic bond and an electrically neutral compound. Also‚ they readily dissolve in aqueous solutions and are good conductors of heat and electricity. Further
