Prelab for Chemistry 111: Experiment 6- An Introduction to Acid-Base Chemistry Mindy McDuffie Statement of Problem Acid rain is a problem for parts of Texas due to the effects of coal burning. In order to better form an opinion for or against the burning of coal, a better understanding of acid base chemistry is required. Summary of Methods In this experiment, the various methods of determining the pH of a solution will be compared. A secondary standard, NaOH and a primary standard, KHP, will be standardized. Titration curves will allow for comparison of the results between the potentiometric determination of the
