Chem 15: Homework Set #1, Part B Chapter 6 6-30. Distilled water has pH of less than 7 because carbon dioxide in the air can dissolve into the water and make it acidic. To prevent this from happening, cover up the beaker so than air cannot get in. 6-43. 6-44. 6-45. 6-47. (a) is a stronger acid, because it has a larger K a value. (c) is a stronger base, because it has a larger K b value. Chapter 7 7-3. 7-4.

7-11. Chapter 8 8-6. 8-11. 8-18. 8-27. The solution reaches a buffer when it contains roughly the same amount of acid (or base) and the conjugate base (or conjugate acid). The concentration of the acid or base present affects the pH very little because the part of the Henderson-Hasselbalch equation is a very small number. 8-28. Because it means there will be more acid (or base) and its respective conjugate base (or conjugate acid). Therefore, it takes more

Unformatted text preview: titrant to use up acid or base. 8-30. Because thats when there is exactly the same amount of acid (or base) and its respective conjugate base (or conjugate acid). Chapter 9 9-2. 9-4. Chapter 10 10-4. 10-7. 10-19. 10-33. A Gran plot uses data from before the end point to locate the end point. 10-36. The indicators transition range is centered at the equivalence point of the acid or base. 10-37. Because thats when the indicators acid (or base) gets all converted into its respective conjugate base (or conjugate acid), which has a different color. 10-38. Taking a sample of the microscopic vesicles, we can find the pH of by matching up with the pH sheet of that particular indicator. 10-40. prior to the equivalence point: yellow. At the equivalence point: green After the equivalence point: blue...
