HOW TO CALCULATE EFFICIENCY OF YOUR LIME BURNING

LIME BURNING PROCESS Introduction The practice of burning limestone to produce quicklime is, almost literally, as old as the hills. In terms of basic chemistry and materials, the process involves the conversion of calcium carbonate, CaCO 3, to the more useful calcium oxide, CaO. Calcium oxide is a very reactive substance.

experimental chemistry How to obtain calcium carbonate

The major synthetic pathway is circular: limestone is mined, then it is heated which produces lime and carbon dioxide. The lime is then mixed with water and C O X 2 is added (bubbled in/through) and C a C O X 3 precipitates. It is then dried. Purification depends on the source; how impure it is to start with.

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
