WebThis is what allows ion exchange to take place. As positively charged cations flow across cation resin beads, the cations are exchanged for hydrogen (H+). Likewise, as negatively charged anions flow across anion resin beads, the anions are exchanged for hydroxyl (OH-). When you combine hydrogen (H+) and hydroxyl (OH-) you form pure H20.
