1.11 How To Get Hooked On Chemistry

How I got Hooked on Chemistry A long time ago I took a course at the University of Connecticut called Advanced Organic Chemistry. Our Professor was Sam Huang, who gave us instructions on the first day and then we rarely saw him again. We were told we had to complete three experiments:Identify an unknown pure chemical samplePurify and identify 2 unknown chemicals in a mixtureCreate a new chemicalHe gave each of us a vial with a liquid or a powder in it. We had three weeks to identify it. Mine contained a shiny white solid. Under a magnifying glass it appeared as flat white plates. It melted sharply at 212 degrees Celsius. A big clue was discovered when I placed it under ultraviolet light- it glowed with a bright blue color. With this information, and by converting it to
