Why does an indicator require precision in the titration process?
Precision in the titration process is important for accurate determination of the end point. An indicator must change color very close to the equivalence point to provide a clear signal for the endpoint of the titration. If the indicator is not precise enough, it can lead to errors in determining the correct endpoint of the titration, affecting the accuracy of the results obtained.
What requirements must be satisfied for a reaction to be feasible for titration?
For a reaction to be feasible for titration, it must be a quantitative reaction, meaning it goes to completion with a known stoichiometry. The reaction must also be fast enough to proceed to completion within a reasonable time frame. Additionally, the reaction should have a distinct endpoint to indicate completion.
Why buffer solution must be used for titration with EDTA?
A buffer solution must be used for titration with EDTA because it helps maintain a constant pH during the titration process. EDTA forms complexes with metal ions at specific pH levels, so maintaining a steady pH ensures accurate and reproducible results. Additionally, a buffer solution helps prevent changes in the pH that could interfere with the formation of the metal-EDTA complexes.
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.
Why must the titration be carried quickly and diffuse?
To minimize the chance of side reactions, errors, or contamination from the surroundings. A slow titration could result in inaccurate results due to reactions with air or impurities. Rapid titration helps to ensure more precise and reliable measurements.

Why the oxidation reduction titration must be in basic medium?
It is not mandatory; acids are also titrated.

Why must the titrations in fajans method be carried quick and iniffuse ligt?
In Fajans method, quick titration is necessary to minimize the effect of background diffusion that could affect the accuracy of the endpoint determination. Using diffuse light helps to prevent any color changes from being obscured, making it easier to visually detect the endpoint in the titration process.
Why must silver nitrate be used in excess in precipitation titration?
Silver nitrate must be used in excess in precipitation titration because it ensures that all the chloride ions in the solution have reacted with the silver ions to form a precipitate (silver chloride). This ensures the endpoint of the titration is reached accurately, allowing for a precise determination of the concentration of chloride ions in the solution.
Is titration a good way to educate teenagers?
Titration involves precise measurements and lots of patience. Takes good laboratory technique is a must. These would be good traits and skills to teach and educate to teenagers.
