Purpose: To determine the percent yield of the precipitate that forms in the reaction between calcium chloride and sodium carbonate. Equipment and Materials: 15 mL 1.0 mol/L Na CO, 1.00 g CaCl, beaker brush 100 mL graduated cylinder two 250 ml beakers electronic balance scoopula two 100 mL beakers funnel 250 ml. Erlenmeyer flask 65 ml water filter paper stirring rod weigh paper paper towel safety goggles Procedure: Using a graduated cylinder, measure 15 mL of 1.0 mol/L sodium carbonate and put it in a 250 ml beaker. Measure 15 mL of water and add it to the beaker and mix. 2. Using an electronic balance, measure 1.00 g of calcium chloride on a piece of weigh paper and put it in a 250 mL beaker. Using a graduated cylinder, measure 50 mL of tap water. Add the water to the beaker and stir with the glass stirring rod to dissolve. Pour the contents of one beaker into the other. Place a funnel into an Erlenmeyer flask. sWeigh a piece of filter paper and record its mass in your observation table. Fold the filter paper into four and place it in the funnel. Pour the products through the filter paper to collect the precipitate. 2. When the filtrate stops dripping, carefully remove the filter paper from the funnel and leave it overnight to dry on the back bench. *Place on a piece of paper towel with your name on it. * The next day, weigh the mass of the precipitate. Subtract the mass of the filter paper Observations: Material Volume of 10 mol/l.Na.co.iml.) Mass of CCI, Mass of dry her papers) Mass of dry filter paper precipitate)
LAB: Percentage Yield: Analyze and Interpret App / 15 1. Write a balanced equation for the reaction that will occur between calcium chloride and sodium carbonate. (Include the states of the substances that actually react). 2. Calculate the theoretical yield for the precipitate that forms in the reaction between 15 mL of 1.0 mol/L sodium carbonate and 1.00 g of calcium chloride. 3. Using the data you collected, calculate the percent yield of precipitate for this reaction. 4. During this lab, you prepared a solution by adding 1.00 g of calcium chloride to 50.0 mL of water. What was the molar concentration of this solution? s. During this lab, you prepared a diluted solution of sodium carbonate by adding 15.0 mL of water to 15.0 mL of 1.0 mol/L Na.Co,. What was the concentration of the diluted solution?
