It is necessary due to the conical flask may not be clean. deionised water is necessary as opposed to water due to the fact that alot of titrations if not all involve ions. if extra ions are added from the water the equivilance point could be off by a few tenths of a ml.
Rinsing in general is necessary due to the fact that you never know what was held in the flask beforehand, and in nearly all cases it would upset your results.
although, if you have no deionised water, it would upset your results less if you cleaned glasswear with normal water than if you used dirty glasswear.
I recently won a competition that was part titrimetric, so I'm confident in my technique as thought by my lab technician.
quick wash with tap water twice, then quick rinse with deionised twice. if anything impure remains, it will be so dilute that it shouldn't affect results.
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.
The solution being titrated is placed in the conical flask. The titrant (the solution being added during titration) is then slowly added to the solution in the conical flask until the endpoint is reached.
Yes, there is a difference between a conical flask and a titration flask. A conical flask is a general-purpose laboratory glassware used for mixing and heating liquids, while a titration flask, also known as a burette, is a specific type of flask used in a titration to measure the volume of a substance being added to a solution. Titration flasks are usually marked with volume measurements to accurately determine the amount of substance added in a titration.
Wetting the conical flask with water during titration helps to ensure thorough mixing and prevents solution splashing or clumping on the sides of the flask. This can help in obtaining accurate and consistent titration results.
yes we use titrant in the conical flask ,this is because titrant is a solution we use in burrete for titration in this process we titrant the solution in the conical flask along with an indicator

Swirling the conical flask during a titration helps to ensure thorough mixing of the reactants, leading to more accurate and consistent results. It also helps to prevent uneven distribution of the indicator or titrant in the solution, ensuring that the reaction proceeds uniformly.
Yes, a beaker can be used instead of a conical flask for titration. However, it is recommended to use a conical flask as it allows for easier swirling of the solution during the titration process, which can improve the accuracy of the results.
The conical flask is not rinsed before performing titration because doing so could dilute the solution and alter the concentration, affecting the accuracy of the titration. It is important to maintain the concentration of the solution as accurately as possible for precise results.
A conical flask is used in titrations because of its narrow neck, which helps prevent splashing and allows for more controlled pouring of reagents. The conical shape also allows for swirling without spillage, aiding in mixing the reagents efficiently. Additionally, the small surface area of the conical flask minimizes evaporation during the titration process.
Yes. By adding water to rinse, you will be changing the concentration of the thing you are titrating, and so your calculation will be off. If you have material on the walls of the flask, just gently stir the flask and let the solution in the flask wash anything off the walls. I do not believe this is true. Once you add an amount of reactant into your flask adding more water will not change the number of moles of reactant that are present in the flask. The titrant will react in the mole ratio for that particular reaction so water doesn't play a role. You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.
So that no extra moles of NaOH were present in the flask.
I believe it is necessary to rinse the conical flask with oxalic acid before use, unless you are sure that the conical flask is really clean and dry before use. However to prevent having any types of unwanted chemical reaction when you pour the oxalic acid in the flask, it is best to rinse it with oxalic acid before use, so that there will not be errors like e.g. there is no pinkish color formed in the solution when you add the color indicator in the oxalic acid when doing titration.
