Dec 2021 21:55:57Determine the Concentration of Acetic Acid in VinegarIn this lab, you will determine the concentration of acetic acid in vinegar using a 0.110 M NaOH standard solution and an acid-base indicator,phenolphthalein.To perform this experiment you will first need to dilute the vinegar by one tenth of the original concentration. Next, add the indicator and then addNaOH slowly to the diluted vinegar solution. Once all the acetic acid has reacted with the base, the first excess drop of NaOH will cause theindicator in the vinegar solution to turn pink. Calculate the concentration of the acetic acid in your vinegar sample ta three significant figures.What is the experimentally determined concentration of acetic acid in your vinegar solution: (Please give your answer to threesignificant figuren)0 682 M Acetic AcidCorrect! Good job.Most cammercial vinegar in the United States is labeled as 5% acetic acid, but can have a mass percentage of between 4.0% and 5.5%acetic acid. What is the mass percentage of acetic acid in your vinegar solution? (Please give your answer to 2 decimal places. Hint: Themolar mass of acetic acid is 60.05 gimol)4.09% Acetic AcidActivate WindowsGo to Settings to acvateCorrect! Good job.

Vinegar contains acetic acid. By titrating this with a base we can easily calculate the…

Amino acids are an important group of compounds. At low pH, both the carboxylic acid group (CO2H) and the amine group (NHR) are protonated. However, as the pH of the solution increases (say, by adding base), the carboxylic acid proton is removed, usually at a pH between 2 and 3. In a middle range of pHs, therefore, the amine group is protonated, but the carboxylic acid group has lost the proton. (This is called a zwitterion.) At more basic pH values, the amine proton is dissociated. What is the pH of a 0.20 M solution of alanine hydrochloride, [NH3CHCH3CO2H]Cl?

Why did the addition of water to the flask not affect the determination of the amount concentration of acetic acid in vinegar?
In the experiment, we used titration to determine the total acid content ofsamples, which we reported in terms of molarity. Reporting acidity through pHmeasurements is quite different, in that we can only measure the amount of theacid in its ionized form. You were tasked to investigate a clear aqueous solutionof an unknown monoprotic acid. You decided to use two methods togather data.Method 1 – TITRATION: A 10. mL aliquot of the sample was diluted with 25 mLdistilled water. Two drops of phenolphthalein were added and then it was titrated3.54 mL of 0.048 M standardized NaOH to the endpoint.Method 2 – pH STRIP: You took 1 mL of the sample and used a pH strip toestimate the pH, which turned out to be around 3.3. Another 1 mL of the samplewas diluted with 9 mL of water. The pH was taken again and is now around 3.8.a) Calculate the molarity of the acid using the titration data.b) If we assume that the titrated unknown is a strong acid, predict thepH of the sample.c) Using pH strip results,…
