Hint: As we know vinegar is obtained by a process called fermentation. that It is found that for the production of vinegar, ethanol or we can say ethyl alcohol is fermented by bacteria from the family called Acetobacteraceae.
Complete answer:
- We can easily define vinegar as a dilute solution of ethanoic acid in water. It is also called acetic acid. It is found that vinegar is a naturally occurring compound which is in the liquid state, hence there is no defined concentration for it. The chemical formula of vinegar is $C{{H}_{3}}COOH$ .
- It is found that the concentration of acetic acid in water is of the range 5% and 20%.
- As we know that vinegar is mainly a diluted solution of acetic acid in water. Due to this reason vinegar is considered as a weak acid. It is found that acid present in vinegar is an organic aliphatic carboxylic acid with two carbon atoms.
- We can draw the molecular structure of vinegar as:
Hence, we can conclude that the correct option is (b), that is the acid present in vinegar is acetic acid .
Note:
- As we know that the acidity of this compound is low, that is it has a very low value of pH, but still the acetic acid does not show complete dissociation in water.
