what is difference between acetic acid and glacial acetic acid_

Glacial acetic acid, a key chemical compound with the formula CH₃COOH, is a colorless, hygroscopic liquid that serves as an important industrial chemical and laboratory reagent. Known for its high purity and distinct sharp odor, glacial acetic acid is often referred to as acetic acid because it is the concentrated form of this compound, containing around 99-100% acetic acid content. The term glacial refers to its ability to freeze at around 16.6 °C (about 62 °F), forming a solid that resembles glacial ice.
