Chart of common organic acids and their formulas

Answer 1

01 Acetic Acid

 Acetic acid is also known as ethanoic acid. LAGUNA DESIGN / Getty Images

Acetic Acid: HC2H3O2

Also known as: ethanoic acid, CH3COOH, AcOH.

Acetic acid is found in vinegar. This acid is most often found in liquid form. Pure acetic acid (glacial) crystallizes just below room temperature.

02 Boric Acid

 This is the chemical structure of boric acid: boron (pink), hydrogen (white) and oxygen (red). LAGUNA DESIGN / Getty Images

Boric Acid: H3BO3

Also known as: acidum boricum, hydrogen orthoborate

Boric acid may be used as a disinfectant or pesticide. It's usually found as a white crystalline powder.

03 Carbonic Acid


 This is the chemical structure of carbonic acid. LAGUNA DESIGN / Getty Images

Carbonic Acid: CH2O3

Also known as: aerial acid, acid of air, dihydrogen carbonate, kihydroxyketone.

Solutions of carbon dioxide in water (carbonated water) may be called carbonic acid. This is the only acid excreted by the lungs as a gas. Carbonic acid is a weak acid. It is responsible for dissolving limestone to produce geological features such as stalagmites and stalactites.

04 Citric Acid

 Citric acid is a weak acid found in citrus fruits and used as a natural preservative and to impart a sour flavoring. Atoms are represented as spheres and are colour-coded: carbon (grey), hydrogen (white) and oxygen (red). LAGUNA DESIGN / Getty Images

Citric Acid: H3C6H5O7

Also known as: 2-Hydroxy-1,2,3-propanetricarboxylic acid.

Citric acid is a weak organic acid that gets its name because it is a natural acid in citrus fruits. The chemical is an intermediate species in the citric acid cycle, which is key for aerobic metabolism.

05 Hydrochloric Acid


 This is the chemical structure of hydrochloric acid: chlorine (green) and hydrogen (white).

Hydrochloric acid: HCl

Also known as marine acid, chloronium, spirit of salt.

Hydrochloric acid is a clear, highly corrosive strong acid. It's found in diluted form as muriatic acid. The chemical has many industrial and lab uses. HCl is the acid found in gastric juice.
