In chemistry labs, burettes—long, graded glass tubes with a stopcock at the bottom—are frequently used to measure liquid volumes precisely. It is essential to the process of titration, which involves reacting a solution with a known volume and concentration of another solution in order to ascertain the concentration of the former. The analyte solution is put in a flask below the burette, which is filled with the titrant solution in a titration. A colour shift or other perceptible change signals the end of a chemical reaction, which occurs when the titrant is gradually released from the burette into the analyte solution. Calculating the volume of titrant needed to reach this endpoint allows one to determine the analyte solution`s concentration. Consequently, during titration tests, the burette is utilised to precisely measure and dispense liquid volumes.
