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.
The true volume is lowered and is not correct.
These air bubbles must be eliminated before a titration.
The presence of bubbles affect the correct volume of the titrant.
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.
Your results are likely to be slightly off. How much off depends on how big the air bubble was and how much titrant you actually used.
Carbon Dioxide CO2 is the bubbles that rise in the air.
Do bubbles escape when you squeeze a sponge under water air
My answer is, that there are air bubbles in the bottom of it, (WHEN ITS BOILING) Than those air bubbles rise to the top, & That's how hot water bubbles more than cold water.
To remove the air bubbles, open the stopcock and the air bubbles will remove

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.
Brakes are bled to remove air bubbles from the brake pipes. Air bubbles in the pipes will make the brakes feel spongy and less efficient.
It is necessary to remove accumulated air from water because if air gets in the gills of a fish, it acts like a block, preventing water in and out
Cold engine. Remove the radiator cap, top it off, start the engine, add coolant as necessary until all air bubbles stop escaping.
Your results are likely to be slightly off. How much off depends on how big the air bubble was and how much titrant you actually used.
No. But air is where the last bubbles went when they popped.
Carbon Dioxide CO2 is the bubbles that rise in the air.
probably just air bubbles. probably just air bubbles. probably just some air bubbles.
You should wedge clay before you work with it, to redistribte the minerals it is made of and remove air bubbles.
No.. sorry ♥ Renee peace out homie ♫
