उत्तर
Acetic acid that contains a very low amount of water (less than 1%) 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 is ice. Removing the water from acetic acid lowers its melting point by 0.2°C.
