Why is pure acetic acid known as glacial acetic acid ?
Answers
Answer:
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 may be prepared by dripping acetic acid solution over a "stalactite" of solid acetic acid (which could be considered to be frozen).
Explanation:
hi mate......
here is your answer.....
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 ice. Removing the water from acetic acid lowers its melting point by 0.2 °C.

Like a water glacier contains purified water, even if it's floating in the salty sea, pure acetic acid sticks to the glacial acetic acid, while impurities run off with the liquid.

It is the second simplest carboxylic acid, after formic acid. The main uses of acetic acid are in vinegar and to make cellulose acetate and polyvinyl acetate. Acetic acid is used as a food additive (E260), where it is added for flavor and to regular acidity. It's an important reagent in chemistry, too. Worldwide, around 6.5 metric tons of acetic acid are used per year, of which approximately 1.5 metric tons per year are produced by recycling. Most acetic acid is prepared using petrochemical feedstock.
