Question

When filling a burette for a titration, how should the burette be adjusted?

1) Horizontally
2) Vertically
3) Diagonally
4) Upside down

Answer 1

2) Vertically. A burette used in a titration should be adjusted vertically for precise volume measurements.

Step-by-step explanation:

When filling a burette for a titration, it should be adjusted vertically. It is essential for precise volume measurements. A burette is a type of liquid dispensing system that accurately indicates the volume of liquid dispensed, and it allows for measurement to the nearest 0.01 mL. To ensure an accurate reading, the burette must be level, and your eye should be at the level of the top of the liquid when making a reading.

Additionally, when reading the volume of liquid in a burette or any graduated measuring device, you should observe the bottom of the meniscus, which is the lowest point on the curved surface of the liquid.
