Lesson 12: Presentaion Thursday 12 August 2010

That day, we were supposed to present our solution to Mr Chang's problem to the class. My group had decided to use evaporation and filtration to achieve our three compounds. I've also learnt other ways of separating the three compounds through other groups' presentation. Mdm Riza had explained that using heat to separate the mixture might not be ideal, as the compounds might be broken down into simpler substances and not the original compounds we want. She also showed us a video on different separation techniques: Magnetism, Filtration and Evaporation. The video is really helpful as it illustrates how the separation experiment is carried out.
