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
Titration is a technique where a solution of a known concentration is used to determine the unknown concentration of a second solution. Typically, the titrant (the known solution) is added from a burette to a known quantity of the analyte (the second solution) until the reaction is complete.burette close burette A piece of apparatus used to add varying but measured volumes of solution during a titration. pipette close pipette A piece of apparatus used to measure accurate and
During a Titration, keep the liquid flowing normally until a few mL from the endpoint (the point at which the color changes). Around the endpoint, allow the liquid to flow drop-by-drop. After reaching the endpoint, rinse and dry the tip of the burette.
