Question

Vinegar is a solution of:
A. $50\% - 60\% $ acetic acid in alcohol
B. $5\% - 8\% $ acetic acid in alcohol
C. $5\% - 8\% $ acetic acid in water
D. $50\% - 60\% $ acetic acid in water

Answer 1

Hint: Vinegar is an aqueous solution of acetic acid and trace chemicals that may include flavorings. Vinegar is most easily manufactured mild acid, it has historically had a wide variety of industrial and domestic uses, such as used in household cleaners.

Complete Step by step answer: vinegar is an acidic liquid produced through fermentation of ethanol by bacteria. Vinegar typically contains $5\% - 8\% $ acetic acid by volume. That means in $100ml$ of water, there is $5 - 8ml$of acetic acid. This accounts for a dilute solution of acetic acid in water.
The conversion of ethanol (${C_2}{H_5}OH$) and oxygen (${O_2}$) to acetic acid takes place by the following reaction.

$C{H_3}C{H_2}OH + {O_2} \to C{H_3}COOH + {H_2}O$

Vinegar has a density of approximately $0.96g/ml$ . The density level of vinegar depends on the acidity of it.
pH level of vinegar is around 2.5. That means vinegar is acidic in nature. Vinegar’s pH level varies depending upon the type of vinegar. Distilled vinegar has a pH level of around 2.5. it can be made from anything that contains sugar.
Vinegar is used as a food preservative.

So, the correct option is C, $5\% - 8\% $ acetic acid in water.

Note: It should be noted that Vinegar has Anti- infective properties. It also acts as an antimicrobial agent. It is used to flavor and preserve foods, heal wounds, clean surfaces and manage diabetes. Vinegar is most easily manufactured mild acid.
