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.
Two solution are mixed, Zn(NO3)2 and Na2CO3. If at the instant of mixing the [Zn(NO3)2]=3.7x10^-5M and [Na2co3]=1.5x10^-6M will a precipitate form?
A solution is made by dissolving 0.100 mols of NaOCl in 100.0 mL of water. The Ka of hypochlorous acid (HClO) is 3.0*x10^-8 at 25.0 C. a.) Write any relevant chemical equations or equilibrium reactions.
