    • 2+, would reduce the extent of ion pair partitioning as it would require the formation of an overall neutral triple ion pair involving two anions pairing with one counter ion, which is costly in terms of entropy, but low aqueous solubility of such salts precludes their use.

    • An even lower pH is possible but the aqueous solubility and hydrolytic stability of compounds needs to be considered in very acidic buffers.
