• Water soluble
• Colorless
• Pungent odour
• Sour to taste

Chemical properties

• Acidic in nature (litmus test): It turns blue litmus to red
• Reacts with base to form salt (reaction with NaOH)

CH₃COOH + NaOH ----------------> CH₃COONa + H₂O
salt

• Reacts with alcohol in acidic medium to form ester (fruity smell of ester)

CH₃COOH + ROH ----------------> CH₃COOR + H₂O
alcohol ester

• Reacts with sodium bicarbonate to evolve CO₂ with brisk effervescence

CH₃COOH + NaHCO₃ ----------------> CH₃COONa + H₂O + CO₂
