AU … Nettet15. jun. 2008 · Answer. 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.

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 ... Nettet13. nov. 2024 · Limestone and dolomite samples (10 fragments of each) were buried into different soil horizons, and after 7 years the loss in weight was measured and expressed in g/100 cm2 of the original surface ...
Nettetfeasible. The consumption of limestone ranged between 20 and 30 per cent more than the stoichiometric requirements. Limestone is a naturally occurring calcium carbonate rock which can react with sulfur dioxide. Limestone can therefore be used for desulfurization of flue gases. The reaction of sulfur di-oxide with dry limestone requires a very NettetSamples were allowed to react for 2 hr, then centrifuged, and the supernatant was saved. Samples were rinsed twice with 18 MΩ deionized water, and wash solutions were added to the leachates and dried down. The soils were then treated with 7.5 ml of 1.5 M hydrochloric acid (HCl) to estimate the U concentration of the HCl dissolvable fraction.
NettetLimestone is a mineral formed of calcium carbonate (CaCO3), which is slightly soluble in water but more so in acid. In this reaction, the limestone reacts with the acid to … NettetWhen a piece of limestone reacts with dilute HCl, a gas X is produced. When gas X is passed thorugh lime water then a white precipitate Y is formed. On passi...
NettetThermal decomposition. When heated above 840°C, calcium carbonate decomposes, releasing carbon dioxide gas and leaving behind calcium oxide – a white solid. CaCO 3 ( s) →. CO 2 ( g) +. CaO ( s) Calcium oxide is known as lime and is one of the top 10 chemicals produced annually by thermal decomposition of limestone.
