The invention relates to a novel process of joint production of sodium carbonate and hydrochloric acid (or hydrogen chloride), belonging to the field of basic chemical industry. The invention solves the problems existing in the sodium carbonate industry and chlor-alkali industry in China at present...
20. To the reaction between calcium carbonate and hydrochloric acid,CaCO_3(s)+2HCl(aq)- →CaCl2(aq) +CO2(g)+H2O(1)The volume of CO2 produced is measured against time. Excessive CaCO3 powder is reacted with 20.0 mL of 2.0 mol dm-3 HCl solution under 25 ℃. The graph of V(CO2)ag...
Topic: Enthalpy Change: Reaction between Calcium Carbonate and Hydrochloric Acid (Read 9477 times) I'm doing a lab on the reaction between calcium carbonate and HCl. My independant variable is the mass of calcium carbonate. So basically, I add in different masses of CaCO3 to show that more ...

Whether it is hydrochloric acid, formic acid or acetic acid, the essence of reaction with calcite is as follows:(4)CaCO3+2H+→Ca2++CO2↑+H2O Usually the reaction between hydrochloric acid and calcite is sufficient, while organic acids such as formic acid and acetic acid have a low hydrogen...
Carbonic anhydrase makes for the formation of acid urine in the kidney, hydrochloric acid in the gastric mucosa, bicarbonates of pancreatic juice in the pancreas, and eggshells (containing CaCO3) in the oviducts of birds. Carbonic anhydrase is specifically and strongly inhibited by sulfonamides, ...
