Calcium carbonate Essential Chemical Industry

Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure. Limestone and other products derived from it are used extensively in the construction industry and to neutralise acidic compounds in a variety of contexts.

The direction of chemical reactions Presenting Science

The direction of chemical reactions. Perhaps the most fundamental question in chemistry is ''why do particular chemical reactions occur?'' Put more specifically, why does one reaction occur while the reverse one does not? For example, if we place a piece of magnesium in dilute hydrochloric acid, hydrogen gas is evolved and magnesium chloride

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 ions will

Calcination Wikipedia

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). 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 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.
