WebTwo types of ion pairs have been recognized, namely, contact ion pairs in which the cation and anion are in physical contact, and solvent-separated ion pairs in which one or two solvent molecules are situated between the cation and anion. Ion pairing must be considered in developing a complete picture of an electrolyte solution. WebExamples of ion pairs include: (i) solvent-separated ion pairs (SSIPs), where the anion is not in the direct interaction field of the cation; (ii) contact ion pairs (CIPs), where the anion establishes an interaction with one cation only; and (iii) aggregates or crystal ion pairs (AGGs), where one anion is coordinated to two or more cations irma\u0027s cafe lewes
