Question: How Would It Affect Your Results If You Use A Wet Erlenmeyer Flask Instead Of A Dry One?

Does adding distilled water affect the results of the titration?

The Properties of Water Water has pH of seven, which is neutral.

When you add it to an acid or base, it dilutes that solution and brings the pH closer to seven.

As long as you account for this dilution in your titration calculations, the addition of water should not cause errors in your results..

How would it affect your results if you use a beaker?

If the beaker you use to measure it out has residual water in it, the water will mix with the solution and change the concentration, making it more dilute. … Therefore, the final concentration of analyte that you calculate will be larger than the actual concentration.

Why does distilled water not affect molarity?

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 does adding distilled water to vinegar sample not affect titration?

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

Why does distilled water not affect titration?

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

Why is the conical flask rinsed with distilled water only?

Answer and Explanation: When doing titrations with aqueous solutions, only distilled water is used to rinse the conical flask so not to leave any residual chemicals in the…

Why does the Erlenmeyer flask have to be dry?

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.

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

Water in the glass of the buret can cause variations in the concentration of the base being used, reason why we rinse it with the base, so we have a good precision titration. The erlenmeyer can be rinsed only with distilled water, since the volume of acid solution used for the calculation is constant.

Why is an Erlenmeyer flask not accurate?

Graduated cylinders, beakers and Erlenmeyer flasks have less accuracy than volumetric glassware. … Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor.

Why use an Erlenmeyer flask instead of a beaker?

Because of swirling. When you titrate properly, you swirl the flask to mix the solutions. Swirling in a conical flask makes the solution run back down, rather than slosh over the edge, so there is less chance of spilling. With a beaker it is more likely that some part of your sample will slosh out.

Why a titration flask should not be rinsed?

The volumetric flask or pipette that you use to load the conical flask must be rinsed with the solution under test to maintain its concentration. Likewise, the burette that you use to add your standard solution during the titration must be rinsed with the standard solution to avoid diluting it.

How do you tell if you have exceeded the equivalence point in your titration?

3. How do you tell if you have exceeded the equivalence point in your titration? – We have to find an indicator which will be able to tell us whether the solution is neutralized into pH 7. The indicator might have different color for each pH. So, it will be able to tell us the pH of that particular solution.
