3. Allow the reaction mixture to equilibrate in the conical flask and maintained at a fixed temperature in a thermostatically controlled water bath (optional water bath) for 1 week. 4. Fill up the burette with NaOH, noting the initial volume reading. 5. Pipette 10.0 cm 3 of the reaction mixture into a 250 cm 3 conical flask containing about 20 cm 3 of ice-cold water to arrest the equilibrium. 6. Carry the titration against NaOH until permanent green colour is obtained from the initial yellow solution quickly so as to ensure minimal changes to the temperature of the reaction mixture. 7. Repeat the steps 1-6 using a different initial reaction mixture of 6 g of CH 3 CH 2 COOH and 3 g of CH 3 OH. NOTE: For this reaction, there is no need for water bath. Enthalpy change of esterification is about zero, based on the estimation of bonds broken and bond formed. Hence there will be no large temperature changes in mixture. Mixture is also expected to be at room temperature of
