Unformatted text preview: esults, repeat the test and/or consult your instructor. Before continuing your work at another station: 1. Complete both Data Tables + 2. Plot a graph for: A) the concentration of [H ] as a function of the Concentration of the Acid for the STRONG BASE. Connect the three data points with a straight line. If the line is not straight (does not cross all data points), repeat your tests and/or consult your instructor. Label this line “STRONG BASE” (Write in the appropriate units on the vertical axis) + 2. Plot a graph for: B) the concentration of [H ] as a function of the Concentration of the Acid for the WEAK BASE. Connect the three data points with a straight line. If the line not straight (does not cross all data points), repeat your tests and/or consult your instructor. Label this line “WEAK BASE” (Write in the appropriate units on the vertical axis) 3. Complete the “SUMMARY OF ACIDIC AND BASIC SOLUTIONS” chart by filling in all the boxes with the respective formulas and concentrations. 4. If time permits you may answer some or all of the questions that follow this section in the laboratory. Otherwise, these questions may be answered at home. PART III: IDENTIFICATION OF UNKNOWN You and your partner will be assigned one unknown each. Record the number of your unknown on the instructor’s sign­ out sheet and in your Laboratory Notebook. Your unknown has a molarity of 0.1 M. Determine the pH of your unknown by using universal pH paper. Since your unknown is in a vial, you may dip the pH paper directly in the solution of the unknown. Make sure...
