Burette Reading Practice

Burette Reading Practice

Carefully read each question and provide the most accurate answer. Pay close attention to the meniscus when reading burette volumes.

Burettes are precision laboratory instruments used to dispense variable, measured amounts of a liquid, especially in titrations. Accurate reading of the burette is crucial for obtaining reliable experimental results.

1. When reading a burette, you should always read the bottom of the  .

2. The smallest division on most standard laboratory burettes is   mL.

3. The initial reading of a burette is often referred to as the   reading.

4. To avoid parallax error, your eye should be   with the meniscus when taking a reading.

1. Describe the proper technique for filling a burette and ensuring no air bubbles are present in the tip.

2. Explain why it is important to record burette readings to two decimal places, even if the markings are only to one decimal place.

1. Which of the following is the correct way to read a burette with a concave meniscus?

1. A burette is read from top to bottom, meaning the volume dispensed is the difference between the initial and final readings.
