1. What is an amphiphilic molecule? How does this property influence the effectiveness of soaps? 2. Why was sud production used to assess the effectiveness of the synthesized soaps? 3. Explain the chemical reaction that occurs between soap molecules and the ions in hard water? How were the synthesized soaps affected by hard water? 4. What is the difference between soaps and detergents? How did the detergent tested in this laboratory compare to the soaps in both distilled water and...

5 in the presence of acid, soaps will undergo the reaction shown below. Explain how this would affect the ability of soap to act as a cleaning agent if it is used in water that is acidic. 6 A friend lives in an area where the tap water is very hard due to high levels of calcium ion. She notices that a bath soap containing sodium palmitate leaves a heavy film of soap scum on her shower. The chemical reaction...

for number 5. my soaps ph is at 11
4. Tristearin and stearic acid are insoluble in water. However, sodium stearate (soap) is soluble. Why is there this difference in solubility? 5. Use of concentrated NaOH (lye or caustic soda) in soap preparations can produce a very basic product. A good soap tests between pH 7 and 9; pH 10 is rather harsh; a pH of 11 means something is wrong. How does your soap compare with these values? How...

Briefly, explain why your 3.0 mL reaction vial and diethyl ether solvent need to be completely dry (free of water)? Support your argument with a reaction equation between your Grignard reagent and water. What does the water do to the phenyl magnesium bromide? Briefly, explain why 3 M HCI (aq.) = [H_3O^+/CI-] hydrochloric acid used instead of a base for the work-up procedure? What did you observe when a low pH was obtained? What was the purpose of NaHSO_3 (sodium...
