Ethanoic acid hazard data

Data also applies to methanoic acid (formic acid) and propanoic acid (propionic acid)

Former name: Acetic acid. The concentrated acid is also known as glacial ethanoic acid. The concentrated acid causes severe burns (do not make the mistake of assuming that a weak acid will not be corrosive). The vapour is very irritating to the eyes and respiratory system. Wear eye protection. If possible, use a fume cupboard when using the concentrated acid.

Irritant hazard warning

Solutions of concentration equal to or greater than 0.4 M but less than 2 M are labelled IRRITANT

Corrosive hazard warning

Solutions of concentration equal to or greater than 2 M are labelled CORROSIVE

Flammable hazard warning

The vapour is FLAMMABLE

Dangerous with: Manganate(VII), nitric acid, peroxides. Violent reactions may occur.

Disposal: Small quantities can be washed down the drain, diluting well with water. Use a fume cupboard if disposing of the concentrated acid in this way.
