CHEM 1A Lecture Notes - Lecture 4: Silicone Oil, Asphyxiant Gas, Reagent
Document Summary
Appendix ii: the in-syringe method for preparing gas samples. The following procedure was adapted with permission from microscale gas chemistry, Gases in syringes may be under pressure and could spray liquid chemicals. Follow the instructions and only use the quantities suggested. Like all gases other than oxygen, it is a simple asphyxiant if inhaled in very large quantities. We will not be generating very large quantities of carbon dioxide. Before we start making gases, we need to know a bit more about the equipment that we will use. Many of the important pieces that we will use are pictured below. Let"s start with the most dramatic, the large syringe which may invoke pangs of fear and memories of visits to the doctor"s office. The syringe is composed for two major parts the barrel (outside part) and the plunger (inside part). On one end of the plunger you will notice an air- tight black rubber seal.
