For divalent-monovalent exchange, show that when a total ion wave passes through a segment of the column, \(\mathrm{y}_{\mathrm{i}, \mathrm{after}}=\mathrm{y}_{\mathrm{i}, \text { before }}\). Hint: Use balance envelope in Figure 20-7B and Eq. \((20-22)\), but with \(\Delta z / \Delta t=u_{\text {total ion }}=v_{\text {inter }}\).
