Plot a graph for: A) the concentration of [H ] as a function of the Concentration of the Acid for the STRONG ACID. 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 ACID” (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 ACID. 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 ACID” (Write in the appropriate units on the vertical axis) 1 Chemistry 52 EXPERIMENT #3 PART II: pH OF BASIC SOLUTIONS Prepare a clean piece of paper towel and four pieces of universal pH paper. Using the dropper from the first reagent bottle (NaOH, 0.1 M) moisten all four areas of the universal pH paper and carefully observe the colors of all four areas of the paper. Compare the colors of the paper to the color chart provided. Record the pH in your Laboratory Notebook. Repeat this procedure for the other three aqueous basic solutions and record the respective pH. Avoid contaminating the droppers or the pH papers. If you are not sure of your observations or if your observations indicate unexpected r...
