Date Soap Name Partner Answer the following questions. • From the pH test, what is one property of soap that you now know? Hint: phenolphthalein turning pink indicates 2. Assume you have washed all NaOH away. 2. The Ca"? and Mg2 tests should have given a solid material with "Your Soap Solution." These solids are insoluble soap salts commonly known as "Bath Tub Scum." • From your results, what can you conclude about the hardness of our tap water? Explain...
What will happen to the pH of the solution if you keep adding NaOH after the end point? e Select one: a. The pH will change randomly. b. The pH stays constant after the end point. c. The pH will increase rapidly. ed. The pH will decrease rapidly.
what would be my percent yield if i retrieved 3.1020 grams of soap? thank you, please show all work. SAPONIFICATION (HYDROLYSIS OF A FAD Fats and edible oils consitute a special class of esters called riglycerides in which alcohol part of the molecule, the trihydroxy compound glycerol, forms with three molecules of various long-chain carboxylic acids (called fatty acids). Ty reactions of simple esters can also be carried out on fats and oils,i acid-or-base-catalyzed hydrolysis. three ester linkages carboxylic acids...
please answer questions 1 & 2 If the following mixtures are incubated at 37°C with the addition of enzymes and/or bile salts, predict if the mixtures would increase in acidity and, if so, which samples increased the most. If the lipids are not digested to a great extent, there would be little change in acidity. Table 5: Testing after incubation with pancreatin or pancreatin and bile salts Test tube Substance Enzyme Prediction of drops of NaOH solution to neutralize (no...
in addition to question 4 what would it be if it were 300millimoles of CaCl2? Question 4 You are experimenting with blood samples and you place a drop of RBCs into a solution of 100 millimales CaCl2. What effect does this have on the RBC Selected Answer: Answers The RBCs would shrink The RDCs would shrink. B. The RBCs would swell and burst. No effect on RBCS. This is an isotonic soution and there would be no net movement of...
What happens if the base (NaOH) is added after the alkyl halide (solution made with 3-chloro-1,2-propanediol and 95% ethanol) during the Williamson ether synthesis? Support your answer with a chemical equation identyfing the side product.
You need to measure pH of a solution known to be made from a metal hydroxide, but you don't have a meter or any indicators. You do happen to have some lead (II) nitrate that is soluble, and you remember that lead (II) hydroxide is insoluble. You add some to 1 liter of your unknown solution and a precipitate forms. You add more until the precipitate stops forming and then a bit more just in case. After you filter and...
A 35.0 mL of a 0.300 M solution of KOH, what is the pH after addition of 35.0 mL of 0.150 M HCl. a. 10.90 b. 11.90 c. 12.90 d. 13.90
only b, d, e, and f. thanks ! Using the what do we call such an output gap! This question involves algebraically solving the system of two equations given by the AD and AS curves. The equations for the curves are given by AD: YAD = 710 - 30P + 5G AS: YAS = 10 + 5P - 2POIL where Y is real GDP, P is the price level, G is the level of government purchases, and Poil is the...
