Still, calcium carbonate ion association can be observed and assessed in this pH regime and is in accord with the literature (SI Table S2). However, at, and below, pH 8.5 calcium bicarbonate association must be taken into account, which is ca. two orders of magnitude weaker than calcium carbonate association, based on the respective …
Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; …
