Assertion :Pure acetic acid is known as glacial acetic acid. Reason: Pure acetic acid freezes a bit below comfortable room temperature that means that when the lab is cold, acetic acid will freeze into pretty white crystal that resemble glaciers.

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Pure acetic acid freezes below room temperature, into white crystal that resemble glaciers so pure acetic acid known as glacial acetic acid.

Anhydrous (water-free) acetic acid is sometimes called glacial acetic acid because it solidifies just below room temperature, at ${16.7}^{o} C$ .

Acetic acid can be concentrated by dripping the impure compound over a "stalactite" of glacial (frozen) acetic acid.

Option A is correct.
