Question

The acid used in the making of vinegar is:
A. Formic acid
B. Acetic acid
C. Sulphuric acid
D. Nitric acid

Answer 1

:Hint: Vinegar is formed with the help of fermentation of specific components. Vinegar is acidic in nature and the acid used in its production should be edible or should not be detrimental to the system. This is why an organic acid is used in this case which helps in the production of the edible component.

Complete answer:
The production of vinegar depends on an organic acid which can be readily used in the different types of food. Vinegar is readily used as a chemical component which can marinate the food and hence while cooking the food the vinegar when introduced can improve the taste. Therefore, in the process of cooking vinegar is an acidic component which is an active ingredient.
Vinegar is formed as a dilute solution of acetic acid and hence the organic acid which is required in this production process is acetic acid $\left( {C{H_3}COOH} \right)$. The acetic acid needs to be produced industrially for the production of vinegar which is widely used in different industries. The production of acetic acid occurs by the process of fermentation where ethanol is converted to acetic acid.
The yeast strains are required for the production of ethanol in bioreactors where the process of alcoholic fermentation takes place. The ethanol produced here is subjected to further fermentation for the production of acetic acid. Therefore, the fermentation by specific bacteria takes place in the second step resulting in the formation of acetic acid. Then the same acetic acid is diluted for the mass production of vinegar.

Hence, option B Is correct.

Note:
Vinegar is widely used in the process of pickling as acidic pH is ideal for the production of a pickle. The same component is used as a salad dressing as well. The use of this ingredient is because it can help maintain normal blood pressure and also helps in weight loss.
