How to read a burette?

view 163

The purpose of burette reading is to tell you how much reagent has been dispensed rather than to tell you how much is in the Burette.

For the Glass Burette, make sure your eye is at the same level as the meniscus to avoid the reading error. For water and most liquids, the meniscus is concave or like U-shape. Read the center of the meniscus or the bottom of the U-Shape. Unlike other volumetric glassware, the zero scale on a burette is written across the top. The measuring scale on the burette is at 0.10 intervals. All burette readings are given to an accuracy of 0.05 mL.

Burette reading

The first and last readings of the burette should be recorded to find the volume of dispensed liquid. The difference between the first and last reading is called the titer.

For electronic burettes, the reading is displayed on the control panel’s screen. It is also recommended to use an electronic burette for the titration process to avoid such reading errors.
