Why does adding distilled water in the conical flask during titration not affect the titration result?

Adding distilled water in the conical flask during titration does not affect the titration result because the volume of the solution in the conical flask affects the concentration of the titrant solution. As long as the same volume of titrant is delivered from the burette and reacts with the analyte, the concentration of the titrant and the volume of the analyte solution will remain the same, ensuring accurate results.


Why must you rinse the titration flask with distilled water before further use?

Rinsing the titration flask with distilled water helps to remove any residue or impurities from the previous titration, which could affect the accuracy of the next titration. It ensures that the flask is clean and free of any substances that could interfere with the reaction being studied. This step is crucial for obtaining precise and reliable titration results.


What is meant by drift in a KF titration?

Drift in a Karl Fischer titration refers to a gradual change in the baseline of the titration curve over time. This can occur due to factors such as contamination of the reagents, improper sealing of the titration cell, or instability in the titration system. Drift can affect the accuracy of the moisture determination and should be monitored and corrected during the analysis.


Why does the volume of water in a titration not matter?

The volume of water in a titration does not matter because it does not participate in the chemical reaction taking place. The key factor in a titration is the concentration and volume of the analyte and titrant being used. The volume of water is often used to dilute the solutions to a manageable volume for titration.


Why is it okay to leave the flasks wet with rinse water for titration?

Water, added after volumetric measuring of the titrant and analyte(s), does not contribute to the amount of titrants to be titrated. It'll only contribute to volume and dilution of the solution(s).

Why doesn't adding water to a vinegar sample prior to titration affect the calculated molarity?

That is a question that confuses many. It is because the water is not acidic and therefore does not affect a colour change. You have a known volume of vinegar when starting the experiment.

Why the titration have to be carried out immediately after the addition of sulphuric acid?

Titration should be carried out immediately after the addition of sulfuric acid to prevent any chemical reactions or changes in the sample that could affect the accuracy of the titration results. Waiting could lead to altered concentration levels or other undesired reactions that could affect the titration process.


What are the products of a strong acid base titration?

The products of a strong acid-base titration are water and a salt. The salt is formed from the cation of the base and the anion of the acid used in the titration.


Why is it important to remove the CO2 from the solutions before doing the titration?

Removing CO2 from solutions is important in titration to prevent it from reacting with the analyte or titrant, which can introduce errors in the results. CO2 can also affect the pH of the solution, leading to inaccurate titration endpoints. By removing CO2, you ensure the titration is more precise and reliable.


Why does a cola soft drink need to be decarbonated to perform a phosphoric acid titration?

Decarbonating a cola soft drink is necessary before performing a phosphoric acid titration because the carbonation can interfere with the accuracy of the titration results. The carbon dioxide gas bubbles can affect the pH of the solution and make it difficult to accurately determine the endpoint of the titration. By removing the carbonation, the titration can be performed more reliably.


Why is it necessary to establish a blank titration before the reaction?

Establishing a blank titration allows you to account for any impurities or contaminants in the titration procedure or equipment, which could affect the accuracy of your results. By performing a blank titration, you can isolate the contribution of these factors and subtract them from your subsequent titration measurements to ensure the accuracy of your results.


Why is distilled water used during titration?

distilled water is used (as opposed to tap water) as it does not contain ions or impurities that may affect the results of the titration, usually by reacting with the acid/alkali themselves or by changing the pH of the solution.As water is pH 7, it is neutral and will not change the pH.
