Question

A. Record and Organize: (68 pts) WEEK 1. 1. Add an entry to the Title Page for this lab report and its page numbers. 2. (2 pts) On the next available blank page in your laboratory notebook write down the date and title of the experiment. 3. (4 pts) Carefully observe your reactant and record your observations. 4. (4 pts) Weigh your reactants and record this data in your laboratory notebook. 5. Read the experimental protocol below: Experimental protocol: • Weigh your solid CaCl2 and add it to a beaker labeled A. • Add just enough water to beaker A to completely dissolve all of the salt. Weigh your solid Na3PO, and add it to a beaker labeled B. Add just enough water to beaker B to completely dissolve all of the salt. Add the contents of beaker A to the contents of beaker B and swirl the reaction mixture for 2 to 3 minutes to allow your products to form. Isolate and weigh the precipitate that forms during the reaction. • Repeat your procedure, as many times as needed to figure out how much Na3PO, is required to fully react with all of your CaCl2. 6. (10 pts) In your laboratory notebook write a procedure for how you will isolate and weigh the precipitate. 7. (4 pts) Record the masses of the precipitate formed during each reaction. 8. (4 pts) Record all observations you make during the experiment. 9. (10 pts) Organize your data into a table that includes all the class data WEEK 2. 10. (20 pts) Organize the class data so that is visually represents the fixed mass ratio of calcium chloride to sodium phosphate. (HINT: Read the background carefully) 11. (10 pts) Write a conclusion in your notebook. Your conclusion should be based on the data from the entire class. In your conclusion you must argue either for or against the law of definite proportions and provide the mass ratio. Laboratory Experiment 5
