What is the main function of burette quizlet?
A burette is used to deliver a measurable volume of solution, dropwise, into a conicl flask containing another solution.
What does a buret measure in?
A buret is used to deliver a measured amount of liquid into a container. You will be using a 25 mL buret with graduations every 0.1 mL. In reading numbers from a graduated scale, you always interpolate between the graduation marks. Since your buret is graduated to 0.1 mL, you will read your buret to 0.01 ml.
Why would a burette be used in an experiment?
Burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.
What is the primary function of a burette chegg?
Question: Burettes A burette is used to measure the amount of solution dispensed. The burette readings are done at the start and finish of the titration and the difference between the volume readings is the amount of solution that has been added to the flask. The volume is read at the bottom of the liquid meniscus.
What are the uses of base burette?
Glass Buret, Base Burette (alkali burette) Burette (Volumetric burette, buret) is a volumetric measuring laboratory glassware which is used in analytical chemistry for accurate dispensing of variable, and for measuring the volume of a liquid, especially of one of the reagents in a titration.
What is the difference between burette and pipette?
A burette is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. Burettes have a stopcock at the bottom while a pipette has a dropper like system that releases liquid in the desired amount by lessening the vacuum.
Why is the burette rinsed with NaOH?
The reason you rinse with sodium hydroxide is because whenever you clean, a small amount of water remains in the buret and it must be cleansed before the experiment begins, or it may alter the values– especially since NaOH is very hygroscopic.
Why is burette called burette?
In 1855, the German chemist Karl Friedrich Mohr (1806–1879) presented an improved version of Henry’s burette, having graduations inscribed on the tube of the burette. The word “burette” was coined in 1824 by the French chemist Joseph Louis Gay-Lussac (1778–1850).
Why is a burette accurate?
Burettes are larger than a pipette, it has a stopcock at the bottom to control the release of liquid. But, it has large meniscus and hence its accuracy and precision is less in measuring liquids. …
What is a burette device used for?

What is the function of a Buret?
A burette, or buret, is a uniform-bore glass tube with fine gradations and a stopcock at the bottom, used especially in laboratory procedures for accurate fluid dispensing and measurement . The buret is commonly used in titrations to measure precisely how much liquid is used.
