How do you determine the concentration of ethanoic acid in vinegar by means of titration?

- Take a sample of the vinegar of known volume (V_a) in a conical flask
- Add your favourite acid/base indicator or prepare a pH meter for use
- Using a burette add a small quantity of a basic solution of known concentration (C_b)
- Mix the resulting solution
- Observe the indicator or use the meter to check the pH
- If the indicator or pH meter shows a "neutral pH" then continue to '7', otherwise go back to step '3'
- From the total volume of basic solution added calculate the concentration of the acid using the relationship C_a*V_a = C_b*V_b that applies at the equivalence point
- Clean up your work area
Repeat all of the above with smaller additions of basic solution (once near to the previously established equivalence point) to increase accuracy. Accuracy can be calculated using the expression that applies at the equivalence point.

How to test for ethanoic acid in vinegar?
Essentially all the acid in vinegar is ethanoic acid, so titration is probably sufficient.
What is hypothesis of a acid base titration?
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
Where do you find ethanoic acid?
Ethanoic acid, more commonly known as acetic acid, can be found in a 5% concentration in vinegar.
Where is ethanoic acid in everyday life?
vinegar is dilute ethanoic acid
Why addition of water to the vinegar does not effect the determination of its concentration in titration?
Yes, it DOES effect the concentration (mol per litre). This is because the volume (of solution, litres) has changed, when diluting, but not the total quantity (just moles of 'reacting' vinegar in the titration).

What is the result for ethanoic acid plus vinegar?
Nothing - vinegar is dilute ethanoic acid.
What is the pH of ethanoic acid?
depends on its concentration.it can be diluted to be pH 4 or 5 and can be concentrated to pH 1 or 2
Is ethanoic acid found in stores?
Ethanoic acid is vinegar.
Is vinegar an alkaline?
Vinegar is an Acid it contains ethanoic acid
Which acid produced vinegar?
Vinegar is produced from Ethanoic acid...
