What is the chemical reaction (equation ?) for the creation of soap from a NaOH solution, fat, and salt water? - soap creations
The instructions for this activity calls for the general chemistry 25 ml of NaOH solution, 25 ml of saline, 10 g shortening, 50 ml of hot water. This is generally the reaction between fat and sodium and sodium chloride play the part?

Soap Creations What Is The Chemical Reaction (equation ?) For The Creation Of Soap From A NaOH Solution, Fat, And Salt Water?

Fat is a triester RCOOCH2RCOOCHRCOOCH2
Word equation fat + liquor ---> soap + glycerin
RCOOCH2RCOOCHRCOOCH2 + 3 NaOH --------->
3RCOONa + CH2OHCHOHCH2OH
The soap is sodium carboxylate RCOO Na +
NaCl solution is used to harden the soap in a process end as flocculation
Rcoones (s) \\ \\ \\ \\ \\ \\ \\ \\ u0026lt ;======> RCOO-(aq) + Na + (aq)
NaCl Na + balance will shift back to the formation of solid soap rcoones
Well, I know, soap is formed by NaOH and fat (eg tristearate),. And there are glycerin and soap.
Gee, if I knew how to make the prices, I write the whole formula.
On the other hand, I'm not sure how the hot water and / or salt has nothing to do with it.
