Burette is used to add titrant to the titrated solution and it has a scale on the side, so that you can precisely measure volume of the added solution. Burette is similar to the pipette, as it is designed to measure volume of the delivered liquid, but it can measure any volume of the solution. If the burette is not completely dry by the time you use it, the remaining traces of water on the inside will make your titrant more dilute and thereby change its concentration. Consequently, if you don't rinse your burette with titrant and there really is some water remaining inside, the titrant you dispense will be more dilute than it should be. 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. 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 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. 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 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. The chaos and production of small bubbles (right) is often capable of driving out all bubbles from the nozzle. If that doesn't work, immerse the nozzle of the buret in a small beaker of titrant and while using the bulb to reverse the flow of titrant, open the valve (right). In both cases use your results to calculate average mass. Quite often single volume pipette and volumetric flask are used together - diluted sample is pipetted from the flask to carry on separate titrations. To calculate sample size we have to multiply titration result by the ratio of the flask volume and pipette volume. A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. 2UJy4.
