Procedure: 1. Put 1.0g of salicylic acid into two clean test tubes. 2. Add 2.0mL acetic anhydride to each tube. 3. Add 0.2g sodium acetate to one tube. 4. Stir mixture with glass stirring rod and replace it with a thermometer. Record the time increment needed for the temperature to increase 4ºC. 5. Clean thermometer with acetone. Let it dry. 6. Add 5 drops of sulfuric acid to the second test tube. 7. Stir mixture with glass stirring rod and replace it with a thermometer as in Step #4. Record the time increment needed for the temperature to increase 4ºC. 8. Put both test tubes into a boiling hot water bath until the solid dissolve completely. 9. Place contents of both test tubes into a 100mL beaker that already contains 50mL of water. 10. Mix the solution thoroughly.
