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.
- When rinsing a buret after cleaning it with soap water should the rinse? When 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 removal of air bubbles is necessary before titration? Answer and Explanation: Good laboratory technique is critical when manually performing titrations. If you have air bubbles in the burette column, then the initial volume will have an error upon reading since part of that volume is occupied by the bubble rather than the titrant.
- Do you have to neutralize muriatic acid? Even in dilute form, muriatic acid can irritate the eyes and skin and cause respiratory problems.

- Why a titration flask should not be rinsed? This is because during rinsing some liquid will remain sticking to titration flask , therefore the pipetted volume taken is the titration flask will increase .
- Is the M1A an accurate rifle? The standard configuration M1A is well known for quite good accuracy. The Springfield Armory M1A Loaded Precision takes things to the next level. Trailing close behind are modern gas guns, or semi-auto precision rifles — usually in the AR pattern.
