In Unit 1 Chemistry students have been studying Organic Chemistry. This involves looking at the properties and reactions of different hydrocarbons (molecules made from carbon and hydrogen). They are testing their solubility in water, as well as their reactions with both acids and bases. Some of the chemicals need to be opened in a fume hood which eliminates the strong odours. Next they will be experimenting with organic compounds such as more hydrocarbons, alcohols and carboxylic acids (this is formed when food starts to go off).
