Calcium carbonate is represented by the chemical formula CaCO3. In a symbol equation, the reaction of calcium carbonate with hydrochloric acid can be written as: CaCO3 + 2HCl → CaCl2 + CO2 + H2O.
The balanced chemical equation for the reaction is: CaCO3 + 2HCl -> CaCl2 + H2O + CO2. Calculate the moles of CaCO3 consumed, then use stoichiometry to find moles of HCl reacted.
This discussion focuses on calculating alkalinity expressed as CaCO3 from various ions, specifically Ca2+, Mg2+, CO2, HCO3-, and CO32-. The calculations provided by the user yield results that are slightly different from the textbook answers due to variations in molar masses used. For instance, the calculated value for Ca2+ is 207.096 mg/L as CaCO3, while the book states 207.25 mg/L. The ...
The discussion revolves around the estimation of the amount of acid required to dissolve 1 kg of calcium carbonate (CaCO3) for the purpose of extracting microfossils from limestone. Participants explore various acids, including acetic, monochloric, and formic acid, and discuss calculations related to molarity and concentration. One participant seeks help estimating the amount of acid needed to ...
