SIXTH EXPERIMENT: Saponification.

• Materials:

1. 900 mL beaker.
2. Spoon.
3. Clock Glass.
4. Bascule.
5. Rod.
6. 32 g NaOH.
7. 90 mL H2O.
8. 270 mL recycled oil.

• Procedure:

We take 32 grams of NaOH in 90 mL water and mix to dissolve you, then let throwing the oil slowly while saponification happens.

• Results:

CH3-(CH2)7-CH=CH-(CH2)7-COOH + NaOH --->  CH3-(CH2)7-CH=CH-(CH2)7-COONa + H2O
