Why is it advisable to remove sodium hydroxide from the burette as soon as possible after titration?
Wiki User
∙ 10y ago
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.

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 will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
Why air bubble is removed burette get before carrying out tit-ration?
If you leave an air bubble in the tip of the burette, you would artificially increase the titration volume needed. This would introduce an error into your calculations and would cause your results to be inaccurate.
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 apparatus is used in titration?
A burette, a pipette and conical flask
Why isn't sodium hydroxide not normally placed in a burette?
Sodium Hydroxide isn't placed in a burette because it is a solid, and burettes hold liquids.
What are sources of error in a titration?
parallax error - reading of volume of 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 titration flask?
It is the conical flask in which the solution from the burette flows into and which you add the indicator into.

Why it is preferred to take acid in burette during acid base titration?
The burette can be filled with either acid or base. The acid will go into the burette only if you want to titrate a base , i.e. you don't know the concentration of the base and want to find out. The solution of known concentration goes always into the burette (in order to be able to measure the volume taken to complete the reaction) and so if you wanted to find out the concentration of an acid you would put the base into the burette.
What do you use a burette for?
The pricipal use is in the volumetric titration - a method of quantitative chemical analysis.
What is the purpose rinsing the burette with distilled water during titration?
Burette is used to measure the accurate value of taking products and we will calculate the lower minuscus and upper minucus of the burrete that's why we using the burette
What is the precaution steps for titration?
Ensure the burette is vertical Titrate slowly when reaching the end point
What science equipment are used during titration?
a burette,a pipette,a beaker,a funnel,and chemical substances
What is a Burette device used for?
A Burette device is used in chemistry for dispensing measured amounts of a chemical solution. It is similar to a pipette both used in titration in analytical chemistry.
