Making Soap.

If I tell you:


Oil, Soda, Soap... Immediately you say: what are you talking about?


You only have to watch this presentation. Click on the picture.





Then, you have to answer these questions:

1.- What's the chemical reaction that forms soap?
2.-Identify the reactives and products in this reaction.
3.- Explain these two properties that are atributed to the soap:
a) Hydrophobic.
b) Lipophilic.
4.- Are you adjusted the reaction? In another case adjust it.
