Question 1 for data analysis 

**Title: Experiment: Precipitation and Limiting Reactants** **Objective:** To observe the precipitation of CaC₂O₄·H₂O from a salt mixture and identify the limiting reactant. **Materials & Procedure:** 1. **Sample Preparation:** - Dissolve a CaCl₂·2H₂O/K₂C₂O₄·H₂O solid salt mixture in ~150 mL of deionized water, adjusting to a basic pH. 2. **Precipitation Process:** - Filter and air-dry the resultant precipitate. - Weigh the dried precipitate to obtain relevant data. **Data Calculations:** **A. Precipitation of CaC₂O₄·H₂O from the Salt Mixture:** - **Mass of salt mixture:** 0.879 g - **Mass of filter paper:** 1.896 g - **Mass of filter paper and CaC₂O₄·H₂O:** 2.180 g - **Mass of air-dried CaC₂O₄·H₂O:** [Result Calculation] **B. Determination of Limiting Reactant:** 1. **Limiting reactant in salt mixture:** CaCl₂·2H₂O 2. **Excess reactant in salt mixture:** [Result Calculation] **Data Analysis Steps:** 1. **Moles of CaC₂O₄·H₂O precipitated (mol):** - Calculation: [Show calculation] 2. **Moles of limiting reactant in salt mixture (mol):** - Follow equation 8.1 3. **Mass of limiting reactant in salt mixture (g):** - Calculation: [Show calculation] 4. **Mass of excess reactant in salt mixture (g):** - Equals mass of salt mixture minus mass of limiting reactant. - Calculation: [Show calculation] 5. **Percent limiting reactant in salt mixture (%):** - Calculation: [Show calculation] 6. **Percent excess reactant in salt mixture (%):** - Calculation: [Show calculation] **Conclusion:** The completion of this experiment allows for the identification of the limiting reactant in a chemical reaction and the analysis of the precipitation efficiency of CaC₂O₄·H₂O. **Notes:** - Ensure accurate recording of all measurements and
