Which of the following correlations about the analyses of iodine and saponification numbers is/are incorrect? a. Alcoholic KOH: dissolve KOH to lipid sample b. Hanus reagent: react with saturated lipid bond c. Reflux set-up: hasten reaction d. Blank titration: determine total mol of KOH 2. A triacylglycerol (Sample X) was subjected to saponification analysis. 1.1 grams of the sample was refluxed with 5% alcoholic KOH and the refluxed solution was titrated with 17.2 mL of 0.44 M HCl titrant. The blank solution was titrated with 25.6 mL of the titrant. i. What is the saponification number of the sample? ii. Which of the following could be the identity of the sample? Show solutions pls a. Tripalmitin (MW: 807.3) b. Trilaurin (MW: 639.8) c. Triolein (MW: 885:4) d. Tristearin (MW: 891.48)

Experiment 6- Milk Objective: 1. Identify the different physical properties of milk. 2. Determine the different constituents of milk. Apparatuses: test tubes, test tube rack, test tube holder, tripod, wire gauze, graduated cylinder, dropper, beaker, watch glass Materials: evaporated milk, litmus paper, filter paper, dilute NaOH solution, Cuso, solution, acetic acid, Benedict's solution, ammonium molybdate solution, AGNO, solution, BaCi, solufion, KCo, solution Mik is an emulsion of fat globules and suspension of casein micelles (Ca, casein, P), all of which are suspended in an aqueous solution. Mik is the only single food that possesses many nutritional values. However, it still cannot be considered as a complete single food because it lacks iron and copper, among other essential nutrients. The proteins are caseins (about 80%), lactalbumin, and lactoglobulin. The fat contains fatty acids ranging from C, to C Other lipids include cholesterol and phospholipids. Lactose constitutes the…
