Acetic acid and phenol are common organic compounds with important applications in both laboratory and industrial production. Although their molecular structures are similar, they have different properties and uses. Below, we will provide a detailed explanation of how to distinguish between acetic acid and phenol

1、 Physical properties 

Acetic acid is a liquid with a pungent odor, with a density of 1.05 g/cm ³， The boiling point is 118 ℃, and it is a colorless liquid at room temperature. Phenol, on the other hand, is a white solid with a melting point of 40-42 ℃ and a boiling point of 181.7 ℃. It appears crystalline at room temperature. Therefore, from the perspective of appearance and physical properties, there is a significant difference between acetic acid and phenol

2、 Chemical properties: Acetic acid has a high solubility in water and can react with bases to form acetate salts. However, phenol has a lower solubility in water and is less likely to react with alkali. In addition, acetic acid has strong corrosiveness and can react with metals to produce flammable gases. Phenol, on the other hand, is relatively stable and less likely to react with metals. Therefore, it is also possible to distinguish between acetic acid and phenol based on their chemical properties

In summary, there are significant differences in physical and chemical properties between acetic acid and phenol. When using and storing, it is necessary to correctly identify and handle according to its nature to avoid accidents.
