(18pts) Properties of Soaps and Detergents From the procedure 1. Prepare 3 small beakers (labeled as instructed below) containing 1 g of solid soap or detergent or 20 drops of liquid soap or detergent and 50 mL of DI water. These samples will be used to test several properties of soap in the experiments below. o Beaker 1-Lab-prepared soap o Beaker 2-Commercial Soap o Beaker 3-Commercial Detergent Alkalinity (Basicity) 2. Add 10 mL of each solution to separate test tubes. 3. Dip a clean stirring rod into each solution and transfer a drop of the solution to pH paper. Record the approximate pH and the color Virtual pH Paper Key 0 1 2 3 4 5 6 7 8 9 10 11 12 13 Virtual pH Paper Key Virtual pH Tests 0 1 2 3 4 5 6 7 8 9 10 11 12 13 pH Paper Appearance Lab-prepared soap Commercial Soap Foam Test 4. Stopper each test tube from the alkalinity test and mix by shaking for ~10 s. 5. A laver of suds or foam should appear. Record your observations. Commercial Detergent Foam Test 4. Stopper each test tube from the alkalinity test and mix by shaking for ~10 s. 5. A layer of suds or foam should appear. Record your observations. Emulsifying Properties 6. Add 5 drops of oil to each of your test tubes from the foam test, stopper each test tube and shake for about 10 s. 7. Compare the sudsy layer that forms to the layer that formed in the foam test. Record your observations.
