Graduated cylinders, pipettes, and burettes are three common instruments used to measure liquid volume. *Graduated cylinders* are used for general measurements due to their versatility, while *pipettes* provide highly accurate volume measurement and are perfect for transferring liquid between containers. *Burettes*, known for their precision, are primarily used in titrations to deliver controlled variable amounts of a liquid.

FAQs & Answers

  1. What is the difference between a graduated cylinder and a pipette? Graduated cylinders are versatile tools used for general volume measurements, whereas pipettes provide precise and accurate volume transfer, ideal for measurements requiring high accuracy.
  2. Why are burettes used in titrations? Burettes allow the controlled release of variable liquid volumes, making them essential for titrations where precise measurement of liquid reagent is crucial.
  3. Can graduated cylinders measure very small volumes accurately? Graduated cylinders are less precise for very small volumes compared to pipettes or burettes, which are designed for higher accuracy in small liquid measurements.
