Today we dove into the chemistry. After a short set of notes on the clues to chemical reactions (hosted by Blue, from Blues Clues) we broke into groups and started experimenting.
We first mixed Ammonium Nitrate with water and found that as the chemical dissolved the test tube became very cold.
Secondly we mixed copper sulfate solution with washing soda and saw a white precipitate form.
For our third experiment we poured some manganese dioxide into hydrogen peroxide--we noticed bubbles of gas which we then tested with glowing splints. The glowing splint relit which told us that the gas was oxygen.
We then mixed baking soda with vinegar--again forming a gas. Our lit splint went out this time which led us to believe that the gas was carbon dioxide.
For our final experiment we dropped some Magnesium metal into a test tube of hydrochloric acid. We again saw bubbling. When we tested this reaction product the results were quite explosive!
