Samantha was tasked to determine the weight percent of potassium carbonate (K2CO3,138.21 g/mol) in a crude sample using hydrochloric acid (HCl,36.46 g/mol) titration method. Assume only potassium carbonate in the crude sample reacts with the HCl. The label on the bottle of the diluted HCl solution on shelf indicated that the solution had concentration of approximately 0.2M. Therefore, Samantha performed standardization of the HCl acid using high purity anhydrous sodium carbonate (Na2CO3,105.99 g/mol) first. Samantha accurately weighed the anhydrous Na2CO3 into a conical flask and dissolved it using 50.00 mL distilled water. She proceeded to titrate the solution using the HCl solution. She recorded the following:
Next, Samantha used the standardized HCl to determine the weight percent of potassium carbonate (K2CO3,138.21 g/mol) in a crude sample. Samantha made the following record: By assembling the necessary apparatus and materials, organize an experiment to determine the weight percent of potassium carbonate (K2CO3,138.21 g/mol) in the crude sample. Report this process with complete details. Your report should include the following:
