Why it is quantitatively not acceptable to titrate each of the vinegar samples?

This is because the readings of the amount of NaOH needed are only valid up to the point when the color pink appears in the entire solution. Titrating beyond that point would produce erroneous values of NaOH volume and molarity of acetic acid.

∙ 13y agoAs soon as the color changes to pink and remains pink, the endpoint has been reached. if you titrate past the endpoint, to where the color becomes dark read, this is going to mess up your calculations on volume of NaOH added and M of acetic acid in vinegar.

How much nitric acid does vinegar have?
Vinegar is the household name for a chemical compound known as Acetic Acid. The kind of vinegar you buy from the grocery store is typically composed of about 5% acetic acid and 95% water (by weight), giving an acid concentration of .83 M.However, this doesn't completely answer the question because some acids are stronger than others. Chemists measure acidity by the concentration of free-floating protons released by the acid. The proton concentration of commercial vinegar is 3.9 x 10-2 M, giving it a pH of 2.4 (low pH = higher acidity). For comparison, lemon juice has an approximate pH of 2.0 and Coca-Cola has a pH of 2.6.So vinegar has a little more acid than coke and a little less acid than your average lemon.
What is the proper handling of vinegar?

What substance could you use to neutralize a solution with a pH of 1.5?
