Why is it alright to use a wet flask for the titration?

It has to be clean and dry so you have the right amount of solution taken out from you flask to be titrated. If it is wet with the solution it does not matter. The conical flask can be wet with distilled water or dry because the moles of the chemical inside the flask is unaffected by the presence of distilled water.

Why doesn’t the conical flask have to be dry or rinsed with the acid to be analyzed?

Why don’t we dry it? This is because since the volume and the concentration of the acid is known. The number of moles added is known to us and this number doesn’t change regardless of how much water is in the flask.

Will rinsing the Erlenmeyer flask sides with water affect the results ie we are determining the concentration of an unknown will this change the concentration?) *?

We were told to rinse the buret with the base so that the concentration won’t be messed up, but when it comes to the flask that is going to hold the acid, there is no need to rinse, because it would not affect the result if it has water in it.

How does water affect titration?

Adding water to a titrant or analyte will change the concentration of that solution. When you add water to a solution, the number of moles of the solvent stays the same while the volume increases. Therefore, the molarity decreases; the solution is diluted.

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

When you add water to the analyte, you dilute a solution of unknown molarity. This dilution ultimately does not affect the experimental results. The concentration of the analyte is still unknown.

Why is conical flask used for titration?

Once the solution is in the pipette, it’s then transferred to a conical flask. Conical flasks are better than beakers for this procedure because they can be easily swirled without risk of the contents spilling. The scale on its side allows the amount of solution that’s been allowed to flow out to be read off.

Can we Rinse the conical flask with the solution to be used in the experiment explain your answer?

No, it is not right. Assuming the conical flask is the vessel in which the reaction takes place, it must be clean. If it is rinsed with distilled water, that’s fine. If it is rinsed with the solution under test that’s not fine – that will affect the number of molecules of reactant in the flask.

Does the addition of water affect the result of the titration explain?

It does not affect the titration reading as water does not react with the reagents or change the number of moles of acid added.

How would it affect your results if you used a beaker with residual water?

1. How would it affect your results if you used a beaker with residual water in it to measure out your standardized sodium hydroxide solution? – Our experiment would not be accurate because there is initially some leftover water inside, which would affect the pH of the acid inside the erlenmeyer flask.

Can water in a conical flask affect the titre values?

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.

Why can’t I use hydrochloric acid to clean my flask?

Probably because the use of hydrochloric acid (which is a reactant involved in this reaction!) could result in some residual aqueous HCl in the flask, which may add to the HCl added later. Anything you use to clean the flask should be inert/not involved in that reaction.

What is the difference between Erlenmeyer flask and volumetric flask?

Erlenmeyer and volumetric flasks are two different tools that have different purposes. An Erlenmeyer flask is essentially just a beaker that is easier to swirl and mix the contained solution. It’s purpose is to hold a solution in a way that is easy to mix.

What happens if you add water to a titration flask?

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.
