Formic Acid vs. Acetic Acid: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 19, 2023
Formic acid, HCOOH, is the simplest carboxylic acid, naturally occurring in ant venom, while acetic acid, CH₃COOH, is vinegar's main component, known for its sour taste and pungent smell.

Key Differences

Formic acid, with the formula HCOOH, is the simplest carboxylic acid. It consists of a single carbon atom. Acetic acid, CH₃COOH, contains two carbon atoms, making it slightly more complex in structure.

Formic acid is naturally found in ant venom, giving it its name (from 'formica,' the Latin word for ant). Acetic acid is most famously known as the key component of vinegar, apart from its industrial synthesis.
