Detailed explanation-1: -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.
Detailed explanation-2: -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.
Detailed explanation-3: -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 very carefully add drops of liquid to a test solution.
Detailed explanation-4: -While burette is used to deliver a chemical solution with a known concentration into a flask, pipette is used to measure the quantity of the analyte-the chemical substrate whose concentration is to be determined.
