Physical properties of ethanoic acid
- A colourless liquid with a sharp pungent smell.
- B.P is #118^oC# and freezes at #17^0C#forming ice like crystals termed as glacial ethanoic acid.
- It is soluble in water and is weakly acidic with a P.H of approximately 4.8.
Note
- Concentrated ethanoic acid is only slightly ionized and is a poor conductor of electricity
- On dilution its conductance steadily improves as the extent of ionization increases
