This experiment was carried out to determine the acidity number in fatty acid. The purpose of determining the acidity number in fatty acid is to obtain the refined oil samples with potential corrosion problem. In conjunction to that, the lower the value of acidity number in fatty acid of a refined oil sample, the better the quality of the refined oil sample. Hence, it is important to know the acidity number in fatty acid of a refined oil in order to distinguish the better one. This ensure one to have a healthier lifestyle.
This experiment determines the amount of sodium hydroxide, NaOH that needed to neutralize a certain measurement of acidity in fatty acid of a two gram of refined oil sample. NaOH played the role as a catalyst in this experiment. A catalyst is used to reduce the amount of the remains and help produce a larger yield of product. Furthermore, isopropanol that was added into the flask containing the refined oil sample is used to dissolve the oil. The flask was then heated to about 40 ̊C on a hot plate to prevent any formation of bubbles and also to completely dissolve the fats. Moreover, a pink colour solution was observed for about 10 seconds after swirling as the titration was carried out. The pink colour will then become colourless as it is

This shows that, among all the six refined oil samples, A1 has the lowest quality oil. In the following ascending order of oil quality after A1 is, A2, A4, A3, A6 and finally A5. Hence, A5 is the highest quality of oil among all the six refined oil samples with lowest amount of acidity in fatty acid. Therefore based on findings, vegetable oils are able to be used as a raw material to supply or fuel a machine or industrial process. At a high temperature, the vegetable oil undergoes hydrolysis to produce fatty acids and glycerol. Glycerin soap are made by recycling the glycerol by
