Today we began our own Chemical I.D. Experiment. It’s called “Mystery Mix.”
The Mystery Mix is a mysterious mix of two chemical compounds, both white powders. Today students began simply by observing. They noticed that the white mystery mix actually had two distinct components: a fine white powder and a larger white crystal.
Later, students tested for a chemical reaction by mixing the substances with water. Although water is non-reactive, it did help the mixing process by quickly dissolving both substances together. The result was a cold, bubbling, fizzing reaction, as seen in the video below.
So now we know we are looking for two distinct white chemicals that react when mixed. Tomorrow, we will narrow down the list further.
