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.
the rate of a chemical reaction increased by a factor of 3.58 when the temp increased from from 35c to 48c. if the
