Today there were a lot of schools in doing the Leaving Cert revision coarse. Therefore Ken was tied up for the whole day with students, so we were with Ria again for the day. For the first part of the morning we worked in the Lab upstairs setting up the desks for an experiment tomorrow. we had to make up the master mix of chemicals which would be used as one of the main chemicals.
After morning break Ruth and I began to set up another experiment called TLC. The experiment is kind of like our junior cert chromatography. We then got to us the UV light to see the spots of chemicals on the paper.
After lunch, Ria introduced us to Dave and Orla, who would be doing the Soap experiment with us again and with a group of students sitting their leaving cert. This time round he experiment made much more sense and I felt I knew exactly what I was doing and why I was doing it. Once our experiment were at the refux stage, Dave showed the test to see it ethanol is produced. Some of the tests were really cool. one test caused the ethanol to form a silver coating on the inside of the test tube.
I felt that I improved my skills today and that I am beginning to learn a great deal about some of the main leaving cert experiments The fact that the collage were running these leaving cert coarse was very beneficial. It gave me an insight into the type of work involved in Chemistry.
