The scale on its side allows the amount of solution that’s been allowed to flow out to be read off. As with the pipette, the burette should be rinsed with distilled water followed by the solution it is to be filled with to avoid contamination issues.
- Why should the burette be rinsed with NaOH before it is filled? Why do you need to rinse the burette with a base before you completely fill it with NaOH? The burette is designed to make precise volume measurements. The accuracy of a titration depends on precision. If any acidic chemical residue was in the burette, it would neutralize some of the NaOH you are using to measure with.
- What do you rinse a pipette with? When you are finished with the pipet in your experiment, rinse with distilled water.
- Why do we rinse burette? To remove impurities from the burette, it is important to rinse it with distilled water. The burette must be rinsed with the titrant to eliminate any distilled water present, ensuring that the solution in the burette is not diluted.
- What could go wrong in a titration experiment? Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette.
- Why should the burette not be completely emptied? When you're cleaning your glassware, you use water to rinse it off. 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.
