I need to calculate the buffer capacity in acid and in a basefrom these data. Then I need to write a short paragraph ( 7sentences) explaining what happen and why one is better buffer thatthe other.
Buffer Capacity = (number of moles of OH- or H3O+ added)
                   (pHchange)(volume of buffer in L)
Buffer capacity in acid 25.0 ml of 0.10M acetic acid and 0.10 MSodium acetate solution
Buffer Volume | 25.0mL |
Buffer pH | 4.5 |
Buffer capacity | |
Vol HCl 0.1M added | Ph |
17mL | 4.5 |
21.4 | 4.5 |
23.6 | 4.5 |
26.5 | 4.0 |
28.4 | 4.0 |
30.4 | 3.5 |
32.3 | 3.5 |
Buffer capacity in base
Buffer Volume | 25.0mL |
Buffer pH | 4.5 |
Buffer capacity | |
Vol NaOH 0.1M added | Ph |
34.9 | 4.5 |
36.8 | 4.5 |
38.6 | 5.0 |
39.9 | 5.0 |
41.5 | 5.0 |
42.8 | 5.5 |
44.1 mL Final volume | 5.5 |
