Why is it necessary to rinse the conical flask with distilled water for titration?

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.

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.
What apparatus is used in titration?
A burette, a pipette and conical flask
Do you use titrant in conical flask?
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
Is there any difference between conical flask and titration lask?
I alsys used a conical flask without any graduations- pyrex for preference- less liable to break.
During titration why use a conical flask and not a beaker?
So you can swirl the contents around without spilling them. =]

Why was the conical flask not washed with the alkali solution it was going to contain during titration?
So that no extra moles of NaOH were present in the flask.
Why do you use conical flask in the titration process rather than beaker?
It prevent the solution from spelling
Why is the conical flask only rinsed with distilled water in the titration procedure?
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.

Is it necessary to dry clean the conical flask before use?
yes
Is it necessary to rinse the conical flask with some standard solution of oxalic acid before use?
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.
What is a conical flask used for?
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type oflaboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side (graduated) to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.
What is a comical flask?
The correct spelling is conical flask. A conical flask is a type of flask that is used in laboratories. They have a conical body, flat bottom, and cylindrical neck.
