Vinegar is also known as
Explanation
Vinegar is a common household substance primarily composed of acetic acid diluted in water, typically at a concentration of 4–8% [1]. In chemical nomenclature, acetic acid is systematically known as ethanoic acid. It is an organic carboxylic acid with the chemical formula CH3COOH. While vinegar is a commercial aqueous solution containing various trace compounds, its characteristic sour taste and pungent odor are derived from its ethanoic acid content [1]. Other options like nitric acid and sulphuric acid are strong mineral acids used in industrial applications such as explosives and batteries, rather than food. Tartaric acid is naturally found in tamarind and grapes but is not the primary constituent of vinegar [1]. Therefore, vinegar is most accurately identified as ethanoic acid in a dilute form.
