Burette: Types, Uses, Advantages, Limitations - Science Info
Feb 2, 2024 · Functionally akin to a pipette, the burette is an essential tool in quantitative chemical analysis, primarily employed to measure the volume of a liquid or gas in experimental procedures. Key features of a burette include its graduated markings along the length of the glass tube, enabling precise volume readings.
17.4: Titrations and pH Curves - Chemistry LibreTexts
Aug 14, 2020 · Plots of acid–base titrations generate titration curves that can be used to calculate the pH, the pOH, the pKa, and the pKb of the system. The shape of a titration curve, a plot of pH versus the amount of acid or base added, provides important information about what is occurring in solution during a titration.
Burette - Wikipedia
A burette (also spelled as buret) [1] is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet.
Acid-Base Titrations - Chemistry LibreTexts
Aug 30, 2022 · Acid-Base titrations are usually used to find the amount of a known acidic or basic substance through acid base reactions. The analyte (titrand) is the solution with an unknown molarity. The reagent (titrant) is the solution with a known molarity that will react with the analyte.

Feb 21, 2021 · A buret is primarily used for titration to determine the concentration of an unknown solution by adding a solution of known concentration. Titration is a type of quantitative analysis and the most common forms are acid-base, precipitation, complexometric, and redox titrations.
Burette | Definition, Description, & Facts | Britannica
burette, 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. On a liquid burette, the stopcock is at the bottom, and the precise volume of the liquid dispensed can be determined by reading the ...
Chemistry A level revision resource: Perfecting acid-based titration ...
Acid-base titrations are used to determine the concentration of a sample of acid or base and are carried out using a piece of equipment called a burette. It is a long, glass tube with a tap at the end which can be used to add drops of liquid very carefully to a test solution.
A microscale acid–base titration | Experiment | RSC Education
Use microscale titration to complete an acid–base neutralisation with sodium hydroxide in this class practical. In this experiment, students use a microscale titration apparatus – prepared from pipettes, a syringe and some rubber or plastic tubing – to carry out a titration, filling the ‘burette’ with hydrochloric acid and placing ...
What is the difference of an acid burette from a base burette?
May 21, 2024 · An acid burette is used to dispense an acid into a solution which provides an excess of hydrogen (H) whilst a base burette is used to dispense an alkaline liquid into a...
