Ion exchange water softeners utilize sodium to stabilize the free electrons or molecules of magnesium and calcium that bond with those of other free molecules. This is due to the fact that the water softeners comprise of resin beads that are negatively charged. Therefore, when the hard water flows through the strongly charged sodium ions, they bond and thus stabilize.
