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.


What happen if you adding water to the titrated substance in the conical flask during the process of titration?

NoUser 1Yes. 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.User 2I do not believe this is true.

You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.User 3No. User 1 means to say that water in the volumetric burette or pipette will effect the concentration of titrant moles. Water in a conical flask will not effect the titre values because the same mole ratios are reacting, and your titre value is measured from the volume remaining in the volumetric burette and not the conical flask. User 2 is correct, although using water to rinse the volumetric burette's contents into the conical flask would adversely effect the results, as volumetric burettes and pipettes are designed to account for the few remaining drops in the instruments. Shaking or tapping the instruments is also a bad idea, as they can easily be broken and doing this would effect your titre values anyway.User 4It will not affect the result at all as long as you use distilled water, as just tap water obviously contains other minerals etc that will affect the results.


How do clean a beaker?

Acid washing it should do. I assume you are in a lab...in which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.


How will you make standard solution?

mix a solute and solvent together and it will make a solution Increase the surface area of the solute with a mortar and pestle. Next measure out the mass of the solute. Add water and increase the temperature and use a magnetic stirrer. Do not fill to the necesary volume. Do not use a graduated cylinder instead use a volumetric flask. Pour solution into the flask. First measure the mass of the flask. rinse the beaker in which the solution was in. add more water to flask and fill to the needed volume. Then find the mass of solution.


How do you rinse shampoo from hair with very soft water?

It is easy to rinse soap off in very soft water. It is hard to rinse soap off in very hard water. You have to rinse and rinse and rinse. And it takes more soap to get things clean in very hard water.

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.

Why need to rinse the walls of the conical flaks with distiiled water before it use?

Distilled water is simply H2O, while normal tap water isn't. Tap water has other minerals that could possibly react with the chemical to be used in the conical flask. Washing with distilled water assures the absence of any unwanted deviation in the result.

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.
