L7. Saponification

Introduction:

Saponification is a reaction that produces soap when you mix and ester and NaOH. 

Material:

- 900 mL beaker.
- Spoon.
- Clock Glass.
- Balance
- stirring rod
- safety goggles
- gloves
- heating plate 
- 32 g NaOH.
- 90 mL H2O.
- 270 g recycled oil.

Procedure:

We mixed in a 600 ml beaker 32 grams NaOH with 90 ml of water, slowly, we noticed that the beaker heated up (it is a endotermic reaction) After that we slowly started to drop the olive oil in the beaker, at the same time mixing the mixture with the stirring rod. We mixed it for 20 minutes, also we heated the beaker on the heating plate to accelerate the reaction. Then we put a couple of drops of aroma and finally we put the soap mixture in a mold.
