Two main observations during the reaction are:
(i) Brisk effervescence
(ii) Sodium acetate is formed
Chemical equation for the reaction is:

Answer:
He must note brisk effervescence.
This is due to liberation of CO2 gas.
CH3COOH + NaHCO3 ------> CH3COONa + H2O + CO2.
When this evolved gas is passed through lime water , it turns milky due to the formation of calcium carbonate.
Ca(OH)2 + CO2 -----> C
