Question:

Chemical equation of limestone and dilute hydrochloric acid

Chemical equation of limestone and dilute hydrochloric acid

Answer:

CaCO3+2HCl=H2O+CO2+CaCl2Limestone is the main component of calcium carbonate, chemical formula is CaCO3Hydrochloric acid is a mixture of hydrogen chloride dissolved in water, the chemical reaction is generally involved in the reaction of hydrogen chloride, chemical formula HCl
CaCO3+2HCl=CaCl2+H2O+CO2 (gas arrow)This reaction is a metathesis reaction (AB+CD=AD+CB)To meet the conditions of double decomposition reaction: 1 two reactants are soluble in water, insoluble in water is a must for another (generally 2) acid product must have precipitation, gas, water, any one of the threeThe above reaction of calcium carbonate is insoluble in water and hydrochloric acid (acid), so the 1 conditions meet; the resultant was CaCl2 and H2CO3, because the H2CO3 is not stable, easy to decompose and produce H2O and CO2, to meet the conditions of 2 (both water and gas), so the reaction can occur
Limestone and dilute hydrochloric acid is strong and the weak, Mr. carbonate, chemical formula H2CO3, but carbonate can decompose into carbon dioxide and water, so the water produced limestone and hydrochloric acid (H2O) and carbon dioxide (CO2) and calcium chloride (CaCl2)
