The purpose of burette reading is to tell you how much solution has been dispensed, instead of telling you how much the burette contains. Unlike other volumetric glassware, the zero scale on a burette is written on top. Measurement scale on the burette is at 0.10 intervals. All burette readings are given to an accuracy of 0.05 mL.
