because otherwise it gives you an incorrect reading. burette measurements are very precise, because you can easily see how many milliliters of substance you are pouring out - air bubbles will interfere with this exact calculation.
To fill a buret, close the stopcock at the bottom, pour the solution into the top of the buret, open the stopcock slightly to allow air bubbles to escape, and then close the stopcock once the solution reaches the zero mark on the scale. Adjust the meniscus by gently tapping the buret if needed.
The final reading is then taken including the bubbles. So if the bubbles are 2 mL and your buret reads 12 mL. It seems like there is 12mL added, but the bubble was not taken into account. So you only pipetted 1o mL yet the bubble made it seem like 12.
If you forget to remove the air bubble from the buret tip, it can affect the accuracy of the titration results. The air bubble can displace some of the liquid in the buret, leading to an incorrect volume measurement of the NaOH solution delivered. This can result in errors in the determination of the unknown concentration of the other solution being titrated.
Removing all the air from IV tubing is important to prevent air embolisms, which can block blood vessels and be life-threatening. The air bubbles can also affect the accuracy of medication delivery.
To remove air bubbles from window clings, gently press and smooth out the cling using a credit card or squeegee starting from the center and moving outwards. You can also puncture the bubble with a needle and smooth it out.
You should dispense a buret rinse through the tip to ensure proper cleaning and prevent air bubbles from forming in the buret. This method also helps to remove any residual liquid or contaminants from the buret.

The buret is a device to preciseely measure volume while being able to deliver a varying amount of stuff. If youare assuming that the volume you have so accurately measured is of, say, hydrochloric acid, and then you end up with an air bubble (not hydrochloric acid) then the precise volume reading on the buret is inaccurate.
To use a buret properly for accurate measurements, first rinse the buret with the solution you will be using to remove any impurities. Then, fill the buret with the solution, making sure there are no air bubbles. Record the initial volume reading. Slowly add the solution to the receiving flask while swirling gently. When you reach the desired volume, record the final volume reading. Subtract the initial volume from the final volume to determine the volume of solution dispensed.
The final reading is then taken including the bubbles. So if the bubbles are 2 mL and your buret reads 12 mL. It seems like there is 12mL added, but the bubble was not taken into account. So you only pipetted 1o mL yet the bubble made it seem like 12.

To effectively remove air bubbles from painted walls, use a small pin to puncture the bubble, gently press out the air, and then smooth the area with a putty knife or sandpaper.
Refilling a buret during titration can lead to inaccurate measurements because it may introduce air bubbles or alter the concentration of the liquid being added. It can also affect the precision and reliability of the titration results by causing variations in the volume of liquid being delivered.
No, warming the slide will not remove air bubbles. To remove air bubbles from a microscope slide, gently tap or press the cover slip down to allow the bubbles to escape. This can be done by applying slight pressure to the edges of the cover slip with a small tool like a needle or a cover glass forceps.
Yes, a hair dryer can be used to remove bubbles from resin by gently blowing warm air over the surface to help the bubbles rise and pop.
