Acetic Acid Glacial (For Molecular Biology) 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 ice. Glacial acetic acid is colorless and is very corrosive. The acetic acid is a colorless, liquid acid (CH3COOH), with a pungent smell and sour taste. Acetic Acid Glacial (For Molecular Biology) is very effective.
