These questions are from an experiment: Fats, soaps and detergents- A saponification reaction
1. The triglyceride and the glycerol differ with respect to polarity and H-bonding. Discuss these two differences in terms of their chemical structures.
We made our own soap and added cottonseed oil, CaCl2, FeCl3, and HCl ( to change solution to ph 4) to see their effects.
When I added the CaCl2 a precipitate formed
2. Write an equation for the formation of any precipitate.
When i added the HCl, the solution became cloudy
3. Write an equation for any changes observed.
