L8: SAPONIFICATION

L8: Saponification

1. Introduction

Saponification is a reaction with a fatty acid with a strong base resulting in a salt of fatty acid soap is called.

This reaction is very important because the fatty acid are insoluble in water, but the soap molecule form micelles which make colloidal dispersions are believed.

2. Objectives

Our goal with our practice is to create a bar of soap.

3. Material

• 2 beakers of 250 mL
• watch galss
• spatula
• stirring rod
• caustic sosa
• water
• oil
• balance

4.Procedure

First of all, we have taken a 250 ml beaker and we put 90 mL of water, we put another beaker 270 mL of oil on a watch glass we put 32 grams of caustic soda.

We put the water i caustic soda and we mixed with a crowbar and we saw that was exothermic. Then we added the oil and we have mazclado until it has been a little more solid. In addition we have added an aroma.

5. Observations

We observed as the mixture of oil, water and caustic soda, has obtained a more solid form.

6. Conclusions

With the mix that we miss, we get soap and let it stand to harden i take shape.
