glacial acetic acid factory_

At room temperature, glacial acetic acid is a viscous, colorless liquid that possesses a pungent odor reminiscent of vinegar. As the pure form of acetic acid, it contains 100% acetic acid content without any water, thus distinguishing it from vinegar, which consists of about 4-8% acetic acid in an aqueous solution. The melting point of glacial acetic acid is 16.6 °C (61.88 °F), causing it to solidify and appear as ice at cooler temperatures, hence the term glacial.

Eiskaltes Essigsäure Stark oder schwach?

However, this does not mean that glacial acetic acid remains indefinitely stable. Over time, even stable compounds can undergo changes due to a variety of factors, including exposure to light, air, and moisture. Glacial acetic acid is hygroscopic, meaning it can absorb water from the environment. This can lead to dilution, which might reduce its efficiency in certain applications. If the acid absorbs too much water, it may not perform as expected in chemical reactions where purity is crucial.
