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.

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 use of a burrtte clamp?
A burette clamp is used to secure and support a burette during titration experiments in chemistry. It helps to hold the burette in place so that accurate measurements can be taken easily and without the risk of it slipping or falling.
What are possible sources of error in a conductrimetric titration experimentWhy is the solution placed in the burette very much more concentrated than that in the conical flask Explain graphs?
Possible sources of error in a conductimetric titration experiment include temperature fluctuations affecting conductivity values, impurities in the solutions affecting conductivity readings, and improper calibration of the conductivity meter. The solution in the burette is typically more concentrated to ensure the endpoint can be easily detected during the titration. In the graphs obtained from the experiment, there is usually a sharp increase in conductivity at the equivalence point, indicating the completion of the reaction between the analyte and titrant.
What is a double burette method?
The double burette method is a technique used in titrations to accurately measure the volume of liquid dispensed during the titration process. It involves using two burettes - one to dispense the titrant and another to collect the solution being titrated. This method allows for precise control and measurement of the volumes of liquids involved in the titration.
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
If a drop of NaOH falls out of the flask during titration, the molarity of NaOH in the flask will decrease. This is because the volume of NaOH solution decreases while the amount of solute stays the same, leading to a lower concentration of NaOH in the remaining solution in the flask.
Which piece of apparatus is used to add dilute nitric acid to potassium hydroxide?
A burette is typically used to add dilute nitric acid to potassium hydroxide in a controlled and precise manner for titration experiments.
Would it matter if droplets of distilled water were left in the burette when it was filled with sodium hydroxide?
Yes, it would matter because any residual water in the burette could potentially dilute the sodium hydroxide solution, leading to inaccurate measurements or titration results. It is important to ensure the burette is completely dry before filling it with the sodium hydroxide solution to avoid any potential errors.
What is the titrant in the burette used for in a titration experiment?
The titrant in the burette is used to react with the analyte in the flask during a titration experiment to determine the concentration of the analyte.
What is alkali burette?
An alkali burette is a piece of laboratory equipment used to accurately measure and dispense alkaline solutions, such as sodium hydroxide or potassium hydroxide, during titration experiments. It is typically calibrated to precise volumes and has a stopcock for controlled delivery of the solution.
Is it necessary to fill nozzle of burette in titration experiment?
Yes, it is necessary to fill the nozzle of the burette in a titration experiment in order to ensure accurate and precise measurements of the volume of liquid being dispensed. This also helps to prevent air bubbles from forming in the burette, which could affect the accuracy of the titration.
How does the use of a burette make a titration precise?
A burette allows for precise and accurate measurement of the volume of titrant added during a titration. The graduations on the burette permit the volume to be read to high precision, enabling accurate determination of the endpoint of the titration. This facilitates precise calculation of the concentration of the analyte in the solution being titrated.
What apparatus is used in titration?
A burette is typically used in titration to deliver a precise volume of a solution into another solution until the reaction reaches completion, as indicated by a color change or other observable change. The burette allows for the careful measurement of the volume of solution added during the titration process.
Why rinse the burette with distilled water?
Rinsing the burette with distilled water helps to remove any impurities or contaminants that may be present in the burette, ensuring that the titrant being used in the titration is not contaminated. This helps to maintain the accuracy and precision of the titration results.
What apparatus is used in a titration experiment?
A burette is typically used in a titration experiment to deliver a measured volume of one solution (the titrant) into another solution (the analyte). The burette is filled with the titrant and the volume of titrant delivered is carefully monitored during the titration process.
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 purpose rinsing the burette with distilled water during titration?
Rinsing the burette with distilled water helps to remove any impurities or residue that may be present inside the burette. This ensures that there are no contaminants that could affect the accuracy of the titration results.
Why ist necessary to rinse the clean burette before filling it with the unstandardised sodium hydroxide solution?
It is important to rinse the clean burette to remove any residual contaminants or impurities that could affect the accuracy of the titration results. Additionally, rinsing helps to ensure that the burette is properly conditioned for the new solution being used. This step helps to avoid any potential errors or inaccuracies in the titration process.
