Within the soil there are metallic as well as hydrogen cations. There is an equilibrium between the cations and the negatively charged colloids on which they are absorbed. The total amount absorbed is called the cation exchange capacity or CEC and varies especially with the clay content and the amount of organic matter. The proportion of the metallic cations in the total CEC of the soil is the base saturation, which may afford a suitable measure of the acidity of the soil. There have been numerous methods used to determine the CEC and the base saturation of soils. 7, record 1, English, - cation%20exchange%20capacity

The exchange capacity of a resin is the total number of equivalents of replaceable hydrogen per unit volume per unit weight of resin, and is determined by the number and strength of fixed ionic groups on the resin. The ion exchange capacity affects solute retention, and exchangers of high capacity are most often used for separating complex mixtures, where increased retention improves resolution. 2, record 4, English, - exchange%20capacity
