  • Calcination - Wikipedia

    In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is CaCO 3 (s) → CaO(s) + CO 2 (g). Today, this reaction largely occurs in a cement kiln.. The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to …

  • What happens when acid reacts with limestone? | Questions ...

    Jun 15, 2008· Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen …
