This process is generally used to remove unwanted ions from a solution without changing the total ionic concentration or pH. The resin can be used in many ionic forms, but in practice the sodium form is almost universally used, due to the resin's relatively low affinity for sodium, which facilitates the binding of other metals, and the low cost of sodium chloride as a regenerant:

R^{-} {Na}^{+} + K^{+} {Cl}^{-} ⇄ R^{-} K^{+} + {Na}^{+} {Cl}^{-}
