Chemistry 11: Types of Lab Reactions

img_0714Experiment #1: We are lighting some magnesium ribbon with the flame of a benson burner. When the magnesium ribbon caught fire it became a mini sun because it was so bright.

 

img_0724Experiment #2: We allowed a butane lighter to run for 5 seconds. A solid blue flame of about 2 inches long and a diameter of 1/2 inch shot out.

 

img_0732Experiment #3: We mixed hydrogen peroxide with some KI crystals. A yellow foam exploded up from the graduated cylinder.

 

img_0710Experiment #6: We put litmus paper in sodium hydroxide and sulphuric acid. In the picture the top is sodium hydroxide, the middle is mixed, and the bottom is sulphuric acid.

 

img_0707Experiment #5: We mixed potassium iodide and lead (ll) nitrate. It became a yellow looking paint with the consistency of water.

 

img_0753Experiment #4: We mixed copper and silver nitrate solution. This is halfway through the experiment and some mold is forming around the copper

 

img_0758At the end of the experiment there is a lot of mold looking crystals and the silver nitrate becomes a lightly tinted blue. Also the copper becomes magnetic towards the crystals when trying to separate.
