Answer :
Final answer:
Quantifying the composition of limestone involves using titration to analyze its chemical composition, specifically to calculate the percentage of calcium carbonate (CaCO3). This process requires precise measurements and a good understanding of stoichiometry Thus option d) To analyze the chemical composition of limestone is correct answer.
Explanation:
Quantifying the Composition of Limestone
The primary purpose of quantifying the composition of limestone is to analyze the chemical composition of limestone, specifically to determine the percentage of calcium carbonate (CaCO3) present in a sample. This analysis is crucial for various applications, including industrial processes and environmental management.
To accurately determine the calcium carbonate content in a limestone sample, a titration method is used. In the provided example, a 0.5413-g sample of limestone is dissolved using HCl, and after expelling CO2, the excess HCl is titrated with NaOH. Based on the volumes and molarities of the solutions used, the percentage of CaCO3 can be calculated using stoichiometric equations. This process highlights the importance of precise measurements and understanding of stoichiometry in quantitative chemical analysis.
