|Odour:Take a small amount of acetic acid in a test tube and detect its odour by wafting.||Pungent smell.||It has an irritating pungent smell.|
|Solubility in water: Take a small amount of water in a test tube and add a small amount of acetic acid to it and shake well.||A homogeneous solution is formed.||Acetic acid is soluble in water.|
|Effect on litmus:Take a small amount of acetic acid in a test tube and dip a strip of blue litmus paper in it.||Blue litmus turns red.||It is acidic in nature.|
|Reaction with sodium bicarbonate: Take a small quantity of sodium bicarbonate solution in a boiling tube. Cork the tube with a double bore cork and insert a thistle funnel into the tube. Then place a boiling tube containing lime water near the tube containing NaHCO3 solution. Insert one end of the delivery tube into the tube containing NaHCO3 solution and the other end into the tube containing lime water. Now, add acetic acid into NaHCO3 solution through the thistle funnel and observe the change in colour of the lime water.||A gas is evolved which turns lime water milky||The gas produced is carbon dioxide due to the action of CH3COOH on NaHCO3, which turns lime water milky.|
