what does "glacial" means in the term glacial acetic acid?

Answer 1

Glacial acetic acid is a trivial name for water-free acetic acid. Similar to the German name Eisessig (literally, ice-vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.7 °C (about 62 °F).

The most common and official abbreviation for acetic acid is AcOH or HOAc where Ac stands for the acetyl group CH3−C(=O)−. In the context of acid-base reactions the abbreviation HAc is often used where Ac instead stands for the acetate anion (CH3COO−), although this use is regarded by many as misleading. In either case, the Ac is not to be confused with the abbreviation for the chemical element actinium.

Acetic acid has the empirical formula C2H4O2. This is often written as CH3-COOH, CH3COOH, or CH3CO2H to better reflect its structure. The ion resulting from loss of H+ from acetic acid is the acetate anion. The name acetate can also refer to a salt containing this anion or an ester of acetic acid.

Answer 3

98% acetic acid will get solidify like a glacial at 16°c..so concentrated acid called as glacial acetic acid....ok
