Learn to safely and conveniently generate eleven different gases for classroom and laboratory use with simple, inexpensive plasticware such as 60-mL disposable syringes. Many of the gases, including hydrogen, carbon dioxide, oxygen, ethyne, ammonia, nitrogen, nitric oxide and nitrogen dioxide are well-suited for microscale laboratory activities for high school and college level chemistry students. Detailed instructions allow for the safe generation of all gases including several of which would normally not be generated in lab or class. The latter are well-suited for classroom demonstrations include sulfur dioxide, chlorine and hydrogen sulfide. All gases are easily prepared without the use of a hood and with negligble risk of releasing smells into the classroom. During this workshop participants will receive a gas generation kit. Participants will practice and master the techniques of gas-generation using syringes and will perform approximately fifteen different experiments using gas-filled syringes. A number of spectacular demonstrations will also be presented. See Microscale Gas Chemistry II. An Intermediate Workshop for additional opportunities.
