Formic acid (chemical formula HCOOH, molecular formula CH2O2, molecular weight 46.03), commonly known as formic acid, is a very simple carboxylic acid. A colorless, irritating liquid. Weak electrolyte, melting point 8.6 C, boiling point 100.8 C. It is very acidic and corrosive and can stimulate skin blistering. It is found in the secretions of bees, certain ants and caterpillars. It is an organic chemical raw material and also used as a disinfectant and preservative.


Acetic acid, also known as acetic acid (36% - 38%), glacial acetic acid (98%), chemical formula CH3COOH, is an organic monobasic acid, which is the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a solidification point of 16.6 () and a colorless crystal after solidification. Its aqueous solution is weak acidic and corrosive. Steam has irritating effect on eyes and nose.


Comparison of acidity between acetic acid and formic acid


The acidity of substances is judged by the hydrogen ion or hydroxide ion ionized in water. The more hydrogen ions ionized, the stronger acidity. This is closely related to the concentration of the substance itself and its environment.
