Strong anion exchangers are designed to remove a variety of anions from solutions, which includes bicarbonate and carbonate ions, the predominant constituents of carbonic acid. Carbonic acid can dissociate in water to form bicarbonate (HCO3-) and carbonate (CO3^2-). A strong anion exchanger has the ability to effectively exchange these ions due to its high affinity for anions, allowing it to remove carbonic acid from solution.

In contrast, weak anion exchangers work less effectively with stronger acids and typically cannot fully liberate the anionic forms of carbonic acid from their solution due to their limited capacity for exchange and weaker bonding. Therefore, the strong anion exchangers are capable of removing carbonic acid and its derivatives, while weak ones generally lack the efficiency to do so.
