| Rough titration | Accurate titration 1 | Accurate titration 2 | Accurate titration 3 | |
|---|---|---|---|---|
| Final reading on burette B in cm3\text{cm}^3cm3 | 24.35 | 23.80 | 24.95 | 26.45 |
| Initial reading on burette B in cm3\text{cm}^3cm3 | 1.15 | 0.55 | 1.80 | 3.25 |
| Volume of sulfuric acid added in cm3\text{cm}^3cm3 | 23.25 | 23.15 | 23.20 |
Calculate the volume of sulfuric acid solution added in the rough titration.
