E-burette is commonly used in the titration process to determine the concentration of an unknown solution. Typically, titrant (known solution) is added from a burette to a known volume of analyte (unknown solution) until the reaction is complete. An indicator is used to find the endpoint of the titration. 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.

A burette is a laboratory graduated glass tube used to deliver measured volumes of liquid to another vessel. It is commonly used for titration in quantitative analysis. In analytical It is used in titrations because it provides accurate volume readings and has a stopcock at the end to control the flow of liquid. What is a Burette? A burette, also called a buret, is a 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 or method 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. Using A Burette. Step 1. Figure 4.9 4. 9: Step 1. A vertical stopcock means the buret is open and a horizontal stopcock means the buret is closed. A helpful tip: the direction of the stopcock follows the direction of the flow. Step 2. Figure 4.10 4. 10: Step 2. Rinse the burette and glassware with the titrant a few times to prevent contamination. The burette is typically used in titrations, a common analytical technique employed in chemistry to determine the concentration of a substance in a solution. With its remarkable precision, the burette allows scientists to add the titrant gradually until the endpoint of the reaction is reached. The digital burette can be used with most common titration solutions (max. 1 mol/l), such as sodium hydroxide, hydrochloric acid or iodine-potassium iodide solution. Certain digital burette models can also be connected to a PC for direct data transfer, thus, eliminating potential data transcription errors. GUTgvB3.
