Answer 2

four to five.

Vinegar is mostly made up of acetic acid (HC2H3O2) and water.

It may also have some spices and herbs. Due to acetic acid, the vinegar has its distinct odor and taste.

The best amount of acetic acid is between 4 and 5 percent in vinegar, by weight.

A greater than five percent of acetic acid may result in a foul-tasting vinegar.

Titration can be used to measure the amounts of compounds that are there in vinegar.
