Anywhere in the world most people use vegetable oil in every area of their life. Food, health, mechanic, hygiene and so on… But how people choose the kind of oil that they will use? How we choose the kind of oil that we will buy when we are in a supermarket? Depending on colour, smell or ingredient? In this case, I became curious about the difference between different kinds of oil and wanted to search for it. After a brief research from supermarkets and Internet I realizied that the amount of oleic acid varies in different types of oil. I preferred to buy Kırlangıç and Kristal brands and 4 different types of oil which included the information about the amount of percentage oleic acid amount at the back of the bottles. This values would be my literature value which I could compare with my values. Oleic acid is a kind of unsaturated acid which exist in different amount in each oil. As oleic acid is a type of weak acid, the most outstanding method is acid-base titration to find the amount in the oil. This experiment could have been done with other methods but I have chosen to use acid-base titration method because I wanted to do the experiment in school laboratory and school opportunities enabled me to do titration method. In order to investigate the introduced topic and find the values of oleic acid my research question is shaped as; what is the difference in oleic acid amounts for different types of oil? Related to my research topic, I also investigated the accuracy and precision of the brands Kristal and Kırlangıç. As a consequence of this experiment, I proved that oleic acid amounts of different oils are distinct. According to this; it is seen that different oils have divergent and various affects on human health.
