Can't we except a white percipitate(ethanoic acid),when ethanoyl chloride is dissolved in water???

No. Ethanoic acid (acetic acid is miscible---soluble in all proportions--- in water).

Thanks!

When ethanoyl chloride (also known as acetyl chloride) is dissolved in water, it typically generates a vigorous reaction due to the strong acid nature of ethanoyl chloride. It reacts with water to produce ethanoic acid (also known as acetic acid) and hydrogen chloride gas. The reaction can be represented by the following equation:

CH3COCl + H2O → CH3COOH + HCl

The resulting ethanoic acid is a colorless liquid and does not form a white precipitate when dissolved in water. The reaction between ethanoyl chloride and water is typically accompanied by fumes, heat, and the liberation of hydrogen chloride gas.

If you are observing a white precipitate in the reaction mixture, it could be attributed to other compounds or impurities present in the ethanoyl chloride sample, or it could indicate the presence of side reactions or decomposition. It is always recommended to handle and perform such reactions in a well-ventilated area with appropriate safety precautions.
