Chemically limestone is Calcium carbonate (CaCO3). So,When it reacts with HCl it forms Calcium chloride and Hydrogen Carbonate. CaCO3+HCl=CaCl2+H2CO3 is a very unstable compound and it readily breaks into Carbon dioxide and Water. Again, CaCO3+H...
Quicklime is known by a wide range of names, like unslaked lime, burnt lime, chemical lime, fat lime, or sometimes just lime. Quicklime is obtained by 'burning' or heating calcium carbonate, which occurs in natural limestone deposits. This process is one of the oldest chemical operations discovered by man, being used all over the world.

Jun 14, 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

May 02, 2013· Calcination reactions usually take place at or above the thermal decomposition temperature. This temperature is usually defined as the temperature at which the standard Gibbs free energy is equal to zero. The decomposition reaction of the limestone is CaCO3= CaO + CO2 (g).
A chemical reaction takes place when the rain (i.e. carbonic acid) meets the limestone (i.e. calcite). The acid H 2 CO 3 and the CaCO 3 combine to form HCO 3 + HCO 3 + Ca. In other words, the calcite is converted to calcium bicarbonate, Ca(HCO 3) 2. This is soluble and is washed away by the rain. Problems caused by acid rain
