If Positive: a dark blue color appear---there is starch in the food being tested. Answer (1 of 10): Saponification is a process by which triglycerides (fats/oils) react with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt known as "soap." In plain English: when you boil fats or oils (in practice usually animal fats or vegetable oils) with sodium . 2ml of the liquid food sample was added to a dry test tube. 1.

Wash the test tube thoroughly before using it for another trial. This observation was probably due to the fact that as the reaction proceeded, the reaction started behaving like a first order reaction. 2. Our main study topic is the saponification mechanisms, in a crucial side reaction of alkali-catalyzed transesterification. To compare the results of tests on the soap prepared in the experiment and a soap prepared commercially . Saponification is a chemical process heavily used in industry, especially in soap production. Table 1 shows the different concentration of ethanolic KOH, . . Table 1 . All right. And we need to use this table to make a scatter plot and a line graph of the data. Around 2800 B.C.E, the ancient Babylon excavations uncovered cylinders with inscriptions for making soap.1 In 1500 B.C.E, records from ancient Egypt described how animal and vegetable oils were combined with alkaline salts to make soap. Add 15 mL of ethanol and 15 mL of 20 % NaOH to the beaker. Vertical Observations Horizontal Observations When needle dropped the needle hit the water and sunk to the bottom of the beaker.
