Calcium carbonate equilibrium pressure must exceed total atmospheric pressure of 101 kPa, which happens at 898 °C. Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO partial pressure as shown below). The equilibrium of its solution is given by the equation (with dissolved calcium carbonate on the right): where the solubility product for [Ca] [CO] is given as anywhere from "K" = 3.7×10 to "K" = 8.7×10 at 25 °C, depending upon the data source. What the equation means is that the product of molar concentration of calcium ions (moles of dissolved Ca per liter of solution)
European Calcium Society Heizmann has sponsored the publication of significant articles in the scientific journal Biochimica et Biophysica Acta. A newsletter is also produced twice a year (May and November). In 2007, ECS launched its first workshop, in Ariège (France). The second took place in June 2009 in Smolenice (Slovakia). European Calcium Society The European Calcium Society is a non-profit society that aims to develop relationships between different generations of scientists in Europe working in the field of calcium signaling and the proteins involved in the Calcium Toolkit. The First European Symposium took place in 1989 and covered calcium binding proteins in normal
