glacial acetic acid and acetic acid_glacial acetic acid and acetic acid

Definition and Properties

The chemical formula for acetic acid is CH₃COOH, with its glacial form being an undiluted version that contains around 99% acetic acid. At room temperature, it exhibits a freezing point of approximately 16.6 °C (62 °F), which is why the term glacial is often used. In its pure form, it can solidify into ice-like crystals, which can be confused with water due to its transparent nature.

With a structure that includes a carboxyl group, acetic acid belongs to a class of compounds known as carboxylic acids. Its acidic properties are notable; it has a pKa of about 4.76, allowing it to dissociate in solutions, releasing hydrogen ions. This is critical for its reactivity in various chemical applications.
