Calcium Carbonate Reacts with Hydrogen Chloride
The reaction between limestone and hydrochloric acid
There is something in the taste, the name of limestone, its quality is strong and stable, and it is mostly stored in mountains and rivers. There is also hydrochloric acid, which has strong corrosion, and its liquid is clear and strong.
When limestone encounters hydrochloric acid, it is like dry firewood meets fire, and the two react quickly. Limestone mainly contains calcium carbonate, and calcium carbonate melts into it when it encounters hydrochloric acid. Looking at its shape, the bubbles are rolling, like the transpiration of boiling soup. This is because the reaction generates carbon dioxide gas, which escapes from the liquid surface, so this is the case. The chemical change of
is expressed in the formula: calcium carbonate ($CaCO_ {3} $) and hydrochloric acid ($HCl $) phase combination, raw calcium chloride ($CaCl_ {2} $), water ($H_ {2} O $) and carbon dioxide ($CO_ {2} $). That is, $CaCO_ {3} + 2HCl = CaCl_ {2} + H_ {2} O + CO_ {2}\ uparrow $.
Calcium chloride dissolves into the liquid, water is a common substance, and carbon dioxide rises and disperses in the air. This reaction is quite common in the field of chemical industry and experimental sites. In the chemical industry, it is used to make calcium chloride or to borrow carbon dioxide for other purposes; in experiments, it is often used to test the properties of calcium carbonate or to study the principle of carbon dioxide generation. From this perspective, the encounter of substances has endless changes, and the wonders of chemistry can be seen.
