September 22, 2022Why should the burette be rinsed with NaOH before it is filled?
September 22, 2022When rinsing a buret after cleaning it with soap and water, should the rinse be dispersed through the tip or the opening on the top? In preparing the buret for titration, the final rinse is with the NaOH titrant rather than the deionized water. Why? When rinsing a buret, the water and rinse should go through the tip.

- Why is it necessary to remove bubbles from the tap and tip of the burette? If an air bubble exits the tip during a titration that volume of air will be registered as some of the volume of titrant that left the buret. This means that the volume of liquid delivered thru the tip will not be the amount calculated by subtracting the final buret reading from the initial buret reading.
- How do you get air bubbles out of a burette? Check the tip of the buret for an air bubble. To remove an air bubble, whack the side of the buret tip while solution is flowing. If an air bubble is present during a titration, volume readings may be in error. Rinse the tip of the buret with water from a wash bottle and dry it carefully.
- What do you clean a buret with? Rinse with distilled water: With the stopcock closed, add some distilled water to the buret. Rinse with solution:. After you are finished with the buret in your experiment, rinse it by filling it with distilled water and allowing it to drain.
- How many times should you rinse a buret? Rinse the buret two or three times with the liquid you wish to use. Do this by adding a small amount of liquid into the buret, turning the pipet horizontally and rotating it so that the liquid contacts the entire inside surface of the buret. Let the liquid drain through the stopcock into a waste container.
- When rinsing a burette after cleaning it with soap and water should the rinse be dispensed through the burette tip or the top opening of the burette Why? After cleaning a buret with soap and water, it is always rinsed with the titrant. In doing so, the rinsing solution must be dispensed through the buret tip as this will help in keeping the concentration of titrant same.
