1 Titrations

2 Learning Objectives Aiming for 4: Accurately read the volume on a burette to 1 decimal place. Identify concordant results Aiming for 6: Calculate a titre. Describe how an indicator can be used to determine the end point. Explain how accuracy can be improved in a titration. Aiming for 8: Justify the use of a pipette and burette for a titration, evaluating the errors involved in reading these instruments. Explain how precise results are obtained in a titration. Justify the use of an indicator in an acid–base titration.

3 Practice Titrations & Safety
You will now have time to practice your titration techniques. Things to remember: Do not take the burette off the wooden support The tip of the burette is very fragile Take particular care when using the pipette filler ~ hold the pipette near the end you are attaching to the filler Hold the volumetric flask by the base and neck when inverting
