Pure ethanoic acid often freezes during winter in cold climates due to its relatively high melting point of 290 K, which gave rise to its name “glacial acetic acid.”

A 5-8% solution of acetic acid in water is commonly known as vinegar and is widely used as a preservative in pickles.

Denatured alcohol is ethanol that has been rendered unfit for drinking by adding poisonous substances such as methanol. Additionally, dyes may be added to color the alcohol blue for easy identification.

Ethanoic acid is commonly known as acetic acid and belongs to a group of acids called carboxylic acids.

Dyes are added to denatured alcohol to color it blue, making it easily distinguishable from consumable ethanol. This helps prevent accidental ingestion of the toxic denatured alcohol.
