Exchangeable acidity is a measure of the amount of a soil's cation exchange capacity (CEC) that is occupied by acidic cations.
By acidic cations, soil scientists generally mean H+ and Al3+, but it can also include Fe and Mn cations. Aluminum and iron cations will combine with OH- ions and take it out of solution, forming an insoluble compound.
Exchangeable acidity is typically reported as a percentage of CEC, or in milliequivalents/100 g of soil.
