Dissolution Behavior
The rate at which a limestone dissolves determines the rate at which ionic calcium (Ca+2)becomes available to react with aqueous sulfur species to form a solid (calcium sulfite/sulfate). The rate of calcium dissolution is a function of the form in which the calcium occurs within the limestone: calcium carbonate, calcium magnesium carbonate or dolomite. The rate of dissolution can be measured using a bench-scale dissolution apparatus.
