Question

to study the physical and chemical properties of acetic ethaoic acid

Answer 1

Physical properties: Pure acetic acid is a colorless liquid with a strong, corrosive pungent odor. Its density is 1.05 g/mL, and boiling point is 118 °C. It has a characteristic sour taste, and is highly miscible in water.

Chemical properties: Acetic acid is a weak acid. As a carboxylic acid, it forms typical derivatives such as acid chlorides, anhydrides, esters and amides. It can be reduced (removal of oxygen or addition of hydrogen) to give ethanol. When heated above 440 °C, it decomposes to give carbon dioxide and methane:

CH3COOH → CH4 + CO2
