Many do, but well known ones are citrus fruits, which all contain citric acid. Also vinegar contains acetic acid.
Acids are classified into two groups: Organic and Inorganic.
Organic acids have chemical formulas they contain carbon (C) and [for the most part] oxygen (O). A few foods with organic acids are:
Apples --- Malic acid (C4H6O5)
Oranges --- Ascorbic acid (C6H8O6) and Folic acid (C19H19N7O6)
Grapes --- Tartaric acid (C4H6O5)
Vinegar --- Acetic acid (C2H4O2)
Soured Milk --- Lactic acid (C3H6O3)
Other acids that DO NOT contain carbon. (*Please note, an acid can contain oxygen and still be considered inorganic. As long as it does not contain carbon, it is classified as inorganic.) Some things with inorganic acids:
Stomach acid --- Gastric acid
Consists mainly of Hydrochloric acid (HCl), but also contains some Potassium chloride (KCl) and Sodium chloride (NaCl)
Soft Drinks --- Phosphoric acid (H3PO4)

Does an organic compound contain nitrogen?
Yes, organic compounds can contain nitrogen. Many organic molecules, such as amino acids, proteins, and nucleic acids, contain nitrogen atoms in their structures.
What 4 types of organic molecules contain nitrogen?
The four types of organic molecules that contain nitrogen are amino acids, nucleic acids (DNA and RNA), proteins, and some vitamins (such as B-vitamins).
Do amino acids contain carbon?
Yes, amino acids are organic compounds that contain carbon, along with hydrogen, oxygen, and nitrogen atoms.
What are the two kinds of weak acids?
The two kinds of weak acids are organic weak acids, which contain carbon atoms, and inorganic weak acids, which do not contain carbon atoms. Organic weak acids include acetic acid and citric acid, while inorganic weak acids include hydrofluoric acid and hydrogen sulfide.
What is a organic acid?
Organic acids are compounds that contain a carboxyl group (COOH) and function as weak acids in chemical reactions. They are commonly found in nature, such as in fruits (citric acid in lemons), vinegar (acetic acid), and other food products. Organic acids play various roles in metabolism, flavoring, and preserving foods.
