Here is a picture taken during Form 5. Guess what are these, these are soups which were prepared in the lab. Interesting huh? Near the end of school, we learnt about saponification which is a process of hydrolysis of fat or oil with alkali to form soap. The day before the experiment, we were told to bring our perfumes to give the soap sweet scent. It was my first time making soap and I felt tremendously excited. First, we were told to dissolve the sodium hydroxide and heat the oil gently in a beaker. Then, we added the solution to the heated oil while stirring it until it hardened. After that, we added some perfumes to the mixture and filtered it to get the soap. It turned out that the soap is much more smaller than I expected, and the smell of oil is stronger than the perfume. Some of my friends brought curry powder and packets of flavoring of instant noodles as their ''perfumes'' to the soaps. Guess what? the soaps had the smell of curry and instant noodle, certainly interesting however, the colour of the soaps were GROSS, that made me feel sick of curry the following weeks. After home, I molded the soap into a lovable shape as in the picture. I gifted to my friends as I have nowhere to keep. Therefore, I took a picture of it as a remembrance of this fun and memorable experiment. I <3 Chemistry !!!
