Given that the average pH of clean, unpolluted rain today is 5.4, determine the pH of unpolluted rain 40 years ago. Assume that carbonic acid (H2 CO3) formed by the reaction of CO2 and water is the only factor influencing pH.

Case Study Section 1 – pH Based on “The Case of the Mortified Mom: Acids, pH and Buffers” by Terry Platt (National Center for Case Study Teaching in Science) The Patient: Paramedics were called to the home of the Mathews family because their 3-year old daughter, Molly, had gotten into the medicine cabinet and consumed a large number of aspirin tablets. When the paramedics arrived Molly had vomited several times, with bits of undissolved tablets visible, but seemed sleepy, almost lethargic. She was rushed to the nearest Emergency Room. When she reached the hospital she was unarousable and was breathing rapidly and deeply. She was examined and lab samples were obtained. Above is the structure of aspirin, or acetylsalicylic acid, which is a weak acid with a pKa of 3.5. The active, and toxic at high doses, form is the protonated form. Question 9: What would be the consequence(s) of lower than normal blood pH? Cause proteins to denature Decrease in enzyme activities Limit…

CH3CH2COOH Draw the Lewis structure of the acid and mark the acidic hydrogen with an asterisk (*). Draw a Lewis structure of the conjugate base of the acid. Suppose the acid is neutralized with a strong base. a) Which of the two structures you drew in 6 and 7 would be the predominant form of the species at a pH well above that at the equivalence point? b) Which of the two structures would be the predominant form of the species at a very low pH, well below that at the equivalence point and similar to the pH near the start of the titration? c) At what point in the titration, if any, would there be equal amounts of the two forms?
