Compound states [like (s) (aq) or (g)] are not required. If CaCO3 adds 1 alkalinity equivalent the RO water's residual alkalinity was lowered by 2.2 dH (~ 50 ppm CaCO3) Water B: 1.5 RO water + 0.23g CaCO3 + 0.23g CaCl2*2H2O. This experiment was about the reaction of CaCO3 and HCl. Calcium carbonate doesn't react with pure water, but it does react with carbonic acid, that is, water with dissolved carbon dioxide, to produce soluble calcium bicarbonate. Titrating to end point of 4.5 pH gives CO3 and HCO3 total. Error: equation CaCO3+H2O=Ca(OH)2+HCO3 is an impossible reaction Please correct your reaction or click on one of the suggestions below: CaCO3 + H2O = CO2 + Ca(OH)2 CaCO3 + H2O = CaO + H2CO3 CaCO3 + H2O = Ca(OH)2 + H2CO3 Instructions and examples below may help to solve this problem You can always ask for help in the forum H 2 SO 4 + CaCO 3 → CaSO 4 + CO 2 + H 2 O. Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO2 partial pressure as shown below). Calcium carbonate is a chemical compound and calcium salt with the formula CaCO3. "Why do calcium carbonate play an important part in Industry? If the CaCO3 weighed 612 g and the CaO weighed 343 g, how many grams of CO2 were formed in the chemistry what volume of 0.1 moldm-3 HCL acid would be required to dissolve 2.3 grams of calcium carbonate equation CaCO3+2HCL----------=CaCl2+CO2+H20 (WATER) Water A: 1.5 l RO water + 0.12g CaCO3 + 0.44g CaCl2*2H2O. The reaction of it was metal carbonate reaction. That is how caves form in limestone, and how stalagmites and stalactites form from dripping water in those caves. CaCO3 (s) + 2 HCl (aq) R CaCl2 (aq) + CO2 (g) + H2O (l) a. 17 February 2008. Equation for CaCO3 + H2O (Calcium carbonate + Water) - YouTube Sulfuric acid - … The formula of it should be CaCO3 + 2HCl → CaCl2 + H2O + CO2.
