Limestone reacts with hcl
Nettet(b) (i) When a piece of limestone or calcium carbonate is treated with dilute hydrochloric acid, carbon dioxide (X) is produced. CaCO3 + 2HCl → CaCl 2 +H 2 O +CO 2 (ii) When carbon dioxide (X), is liberated in the reaction and is passed through lime water, the lime water turns milky or a white precipitate of calcium carbonate is formed. NettetHCl → H + + Cl -. This means that the concentration of H + ions in 0.4 M HCl is higher than that in 0.4 M ethanoic acid, so its pH is lower and its acid reactions are faster. When alkalis are added, however, the ethanoic acid equilibrium position moves to the right, so eventually all the acid reacts, as shown in the equations below: NaOH ...

Nettet28. feb. 2016 · With sulfuric acid, the highly insoluble calcium sulfate is formed on the surface of the marble chip. With other words: Calcium sulfate acts like a protective layer. C a C O X 3 reacts with H X 2 S O X 4 but he reaction does not go further due to the formation of the layer of C a S O X 4 on the surface of C a C O X 3. NettetHydrochloric acid (HCl) is commonly removed from flue gases using hydrated lime (Ca(OH)2) as a sorbent in the dry scrubbing process. Although this method is relatively easy to operate and the lime sorbent is cheap, this process is highly inefficient, as only ∼25% of the lime used is converted, due to the short contact time and the lack of …

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.
