Question

Which acids are naturally found in foods and can be safe to eat? Check all that apply. sulfuric acid citric acid hydrochloric acid nitric acid acetic acid

Answer 1

Answer: citric acid , acetic acid

Step-by-step explanation: Acids are substances which when dissolved in water give
`H^+` ions.

The acids are of two types based on their origin:

1. Mineral acids: are inorganic compounds composed of different chemical element combinations. They are synthetically produced in labs and are usually strong. Example:
`HCl`,
`H_2SO_4`

2. Organic acids: are organic compounds essentially composed of carbon and hydrogen atoms. They are found in nature and are generally weak.
`CH_3COOH`.

Citric acid
`C_6H_8O_7` is found in citrus fruits and acetic acid
`CH_3COOH` is found in vinegar and are safe to eat.

Answer 2

Answer : The correct answer is- citric acid and acetic acid.

Citric acid
`(C_6H_8O_7)` is a weak organic acid that is found naturally in different types of citrus fruits such as grapes, orange, berries, lemon.

It is used in food to give sour flavour and as a preservative ( such as in gems, pickles) to prevent the growth of bacteria.

Acetic acid
`(CH_3COOH)` is a second simplest carboxylic acid that is a weak organic acid. It is found naturally in fruits such as grapes, pineapple, strawberries. It is safe to eat if used in proper manner ( such as dilute acetic acid, which is vinegar, is used as preservative in food).
