WebIon Exchange Process In the following ion exchange process, a lithium cation displaces a potassium cation from the organic anion, R- : (1) K R + L i + ⇋ L i R + K + We can imbed the lipophilic R- in a membrane, as shown in Figure 2, and place it in a solution of Li+ (2) K R ( m e m) + L i ( a q) + ⇋ L i R ( m e m) + K ( a q) + Figure 2. WebTaking sodium chloride (NaCl) to represent inorganic salts in water, the working principle of ion exchange resin is as follows: Cation exchange resin: R—H + Na+ —— R—Na + H+ …
