Question

Which of the following acid is present in vinegar:
A. Hydrochloric acid
B. Acetic acid
C. Tartaric acid
D. Citric acid

Answer 1

Vinegar has one of the following acids in its content in 5-8 % proportion. And acid is formed by the oxidation of ethanol generally by some acid bacteria. Vinegar is commonly available in almost every grocery store in the country.

Complete answer:
- Vinegar is a dilute solution of acetic acid also known as ethanoic acid in water. Acetic acid is formed by the oxidation of ethanol generally by acetic acid bacteria, and, in most of the countries, commercial formation includes a double fermentation where the ethanol is formed by the fermentation of sugars by yeast.
- Vinegar (also known as dilute acetic acid) is commonly available in almost every grocery store in the country. The large one gallon jugs can be easily found in households almost everywhere. One magazine published an article including a number of ways to use vinegar in daily life, from cleaning dirt off your laptop to cleaning window blinds. A mixture of vinegar and baking soda is known as an excellent way to clean sink drains. We can also clean our carpets and our piano keys.
Hence, Vinegar contains acetic acid which is also known as ethanoic acid.
- Acetic acid also known as ethanoic acid, which is the most important of the carboxylic acids. A dilute (which is around 5 percent by volume) solution of acetic acid formed by fermentation and oxidation of natural carbohydrates is known as vinegar; a salt, ester, or acylal of acetic acid is generally known as acetate.

Thus, Option B is correct.
Note: Breathing higher levels of acetic acid can create irritation of eyes, nose and throat, cough, also chest tightness and stiffness, headache, fever and mental confusion. In a few serious cases it can damage the airways, a fast heart rate and eye can be damaged. An accumulation of fluid in the lungs may also occur and which may take up thirty six hours to form. Vinegar is actually an aqueous solution of acetic acid and few trace chemicals which may involve flavourings. Generally the acetic acid is formed by the fermentation of ethanol or sugars by acetic acid bacteria. Vinegar contains only one of the following acids which is acetic acid and it is also known as dilute acetic acid. Vinegar is a dilute solution of acetic acid also known as ethanoic acid in water. Acetic acid is formed by the oxidation of ethanol generally by acetic acid bacteria.
