2-4 Elements and Compounds

Today's class we did two main experiments. The pickle electroloysis and the sugar and sulfuric acid dehydration demonstration. We saw in the pickle electroloysis what happens when the compound splits apart into its constituent elements. The sugar and sulfuric acid dehydration was by far the highlight of the class. When Mr. Doktor first added the sulfuric acid and the sugar turned a brownish colour, it really wasn't all that exciting. Without warning however, the sugar rose up as a black solid and gave off a strong scent which had everyone coughing and laughing. Following the two demonstrations, I had to leave for volleyball so I wasnt there for the acids and bases notes. I'll be getting the notes from Jarren so those will be put up soon. Here is a quick video that re-enacts our dehydration demonstration. http://www.youtube.com/watch?v=uaB70TgLfqs

That is all. Mr Doktor is the best!
