Formula CH3COOH

Acetic acid that contains a very low amount of water (less than 1%) it is called anhydrous (water-free) acetic acid or glacial acetic acid. The reason it's called glacial is because it solidifies into solid acetic acid crystals just cooler than room temperature at 16.7 °C, which ice.
