- 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.
- 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?

If any acidic chemical residue was in the burette, it would neutralize some of the NaOH you are using to measure with.

Adjust the values to fit your image. A high-resolution image requires higher values for "Amount" and pixel "Radius." Click "OK" to apply the Unsharp Mask.
- 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.
- How do you get dried paint out of an airbrush? CLEAN THE NOZZLE AND CAPS To loosen paint, soak your nozzle, needle cap, nozzle head cap (if compression nozzle) and nozzle cap in Medea Airbrush Cleaner (or solvent) for NO MORE than 10 minutes.
