1. Prolonged skin contact with glacial acetic acid may result in tissue destruction. 2. When undiluted, it is sometimes called " glacial acetic acid ". 3. "Glacial acetic acid " is a name for water-free ( anhydrous ) acetic acid. 4. _Glacial acetic acid , a glass solvent. 5. Glacial acetic acid is used in analytical chemistry for the estimation of weakly alkaline substances such as organic amides.6. Chromic acid in glacial acetic acid solution oxidizes it to picene-quinone, picene-quinone carboxylic acid, and finally to phthalic acid. 7. It can be prepared by slowly adding excess bromine to a hot solution of phenolsulfonphthalein in glacial acetic acid . 8. Glacial acetic acid is a much weaker base than water, so the amide behaves as a strong base in this medium.9. It then can be titrated using a solution in glacial acetic acid of a very strong acid, such as perchloric acid. 10. It can be synthesised from fluorenol with the addition of glacial acetic acid and sodium hypochlorite solution, undergoing an oxidation reaction.
