Question
What is Vinegar? How will you get glacial acetic acid?
✓

Answer

  1. Vinegar is 6 to 8% solution of acetic acid in water.
  2. Pure acetic acid is called glacial acetic acid. Because it forms ice like crystal when cooled.
When aqueous acetic acid is cooled at 289.5 K, acetic acid solidifies and forms ice like crystals, where as water remains in liquid state and removed by filtration. This process is repeated to obtain glacial acetic acid.
