Why 27 degrees Celsius written on burette?
On the burettes (also pipettes, volumetric flasks, etc.) is marked the calibration temperature; but this temperature is 20 0C.
Why is it advisable to remove sodium hydroxide from the burette as soon as possible after titration?
Sodium hydroxide, particularly highly concentrated sodium hydroxide, can dissolve glass if left sitting long enough. Therefore, if you leave the sodium hydroxide in the burette after finishing your titration, you could increase the volume inside the burette from the glass being dissolved from the inside out. This would make the burette measure the titration volume inaccurately and would invalidate the results of future titrations done with this instrument.
How do you clean pipette?
First remove all the solid particles from the burette using a scrubber. Then wash the burette with tap water followed by distilled water thoroughly (even the nozzle). Then wash the burette with the solution to be used in the burette.
What is a burette?
A burette is a glass tube with fine gradations and a stopcock at the bottom, used in laboratory procedures for accurate fluid dispensing and titration.
What is the zero reading of a vernier caliper?
on the very top of the burette. Should start from zero to 100mL on the burette

What instruments holds the burette?
A ring clamp is used to hold a burette.
What is Relative standard uncertainty in burette?
The smallest possible burette reading is 0.10 and the uncertainty of a burette's reading is half of its smallest value (0.05).
What is the pupose of a burette?
A burette is used to very accurately measure liquid volumes.
Which is most accurate burette beaker measuring cylinder and volumetric flask?
burette

What is is the use of burette holder in chemistry lab?
In analytical chemistry so many experiments are to be carried out to analyse the chemical properties of solutions/substances. The accuracy of analysis depend on the accuracy of iteration. An accurate reading is possible when it is fixed at perfect vertical position. In order to hold burette in a perfect vertical position during experiment a clamp must be used.
Which apparatus would you use to measure a 25 cm cube liquid?
Burette
What is an acid burette?
If you have an acid in your conical flask then the base will go into the burette. The burette is used to measure the amounts of base you are adding and therefore you will be able to determine the end point which is normally determined by a colour change.
Why rinse the burette with distilled water?
To remove any trace of other chemicals that may still be in the burette.
