Hello, I have an answer with this but I don't know if I'm correct... My answer is 0.508 g, can you calculate if my answer is correct? calculate the given problem using Hasselbach Equation. acetylsalicylic acid is absorbed from the stomach in the free (nonionized) acid form. If a patient takes an antacid that adjusts the pH of the stomach contents to 2.95 and then takes two 5-grain aspirin tablets (total 0.65 g), how many grams of aspirin are available for immediate absorption from the stomach, assuming immediate dissolution? Also assume that aspirin does not change the pH of the stomach contents. The pKa of aspirin is 3.50, and its formula weight is 180.2.

The solution starts off acidic due to the acetic acid present. As more and more sodium hydroxide is added the acid is neutralized. At the equivalence point the amount of acid and base are exactly equal. If more sodium hydroxide is added nothing happens, the reaction is over and the solution remains neutralized The solution becomes basic The solution is still acidic, there is just more volume

Cancel RESET Done The pH of orange juice is typically 3.5, whereas the pH of tomato juice is usually 4.5. This statement implies that the molar concentration of hydronium ions in tomato juice is times that of hydronium ions in orange juice. [Provide a numerical answer such as "10" or "0.005". Do not use scientific notation. Note that for numbers less than 1, use the cosmetic zero before the decimal place "0.005"-- do not write ".005"] · $ Adjust Filters Crop | | | |

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…
