Formic Acid

Formic acid (chemical formula HCOOH, molecular formula CH2O2, molecular weight 46.03), commonly known as formic acid, is the simplest carboxylic acid. Colorless liquid with pungent odor. Weak electrolyte, melting point 8.6℃, boiling point 100.8℃. It is very acidic and corrosive, which can stimulate skin blistering. Exist in the secretions of bees, certain ants and caterpillars. It is an organic chemical raw material, also used as a disinfectant and preservative.
