P8. saponification

Introduction:

• Let's take a saponification. We will create soap from olive oil (a Triglyceride) and a strong base (NaOH). The base plus lipid react and create soap.

Materials:

1. 600mL Beaker
2. Spatula
3.  Watch glass 
4. Stirring rod
5. 2 beakers 250mL
6. electronic balance
7. Gloves
8. Safety goggles
9. Hot plate
10. 32g NaOH
11. 90mL H2O
12. 270mL Oil

Procedure:

• We take 32 grams of NaOH in 90 mL water and mix. Add 270 mL of oil and mix until well dissolved. We can help a heat source. Once dissolved, add scents to smell the soap. Finally pour our solution into a mold and let stand for several days until they solidify. We remove the mold and you're ready to use this soap to wash our hands!
