Study Notes
Titration Instruments
- A burette is commonly used in titrations and volumetric analysis due to its precision in measuring the volume of solutions.
Accuracy of Burettes
- Several factors influence the accuracy of a burette including:
- Calibration - regular checking against standard solutions ensures measurements are precise.
- Temperature - affects liquid density and expansion, potentially altering volume readings.
- Filling technique - proper filling and removal of air bubbles are crucial for accurate results.
Burette Graduation
- Burettes typically feature volume graduations of 0.1 mL or 0.01 mL, allowing for precise measurement of liquids during titrations.
Pipette Types
- A serological pipette is commonly used for general liquid transfers due to its ease of use and versatility in transferring various volumes.
- A volumetric pipette is designed to deliver a single specific volume, ensuring accuracy for precise measurements.
Accuracy of Pipettes
- Serological pipettes have a typical accuracy range of ±0.5% to ±1% depending on the specific design and manufacturer, making them suitable for many applications.
