HAZARD ALERT: In solid form (solidified carbon dioxide— commonly known as dry ice) is very damaging to skin and eyes. Storage: A cabinet dedicated to bottled gas storage.
Disposal: Completely empty lecture bottle in an operating fume hood then follow #26a.
Shelf Life: Indefinite
Soluble: Slightly soluble in water, hydrocarbons, and most organic solvents.
Color and Odor: Colorless, odorless solid.
CAS No. 124-38-9
Carbon Dioxide Gas Preparation: CO2 gas can be produced from dry ice. One to two pounds of dry ice should provide sufficient gas for 40–50 students. You will have to set up a generator apparatus that will enable you to heat the dry ice by placing chunks in a water bath. The evolution of gas is not sufficient unless warmed by water. Your delivery tube (from the generator) should be rather long to allow the gas to reach room temperature. A drying tube will also have to be part of the apparatus to remove moisture.
Some instructors set up a CO2 generator using a flask (about 250 mL size) into which is placed a long-stem funnel and delivery tube. Using about 25 grams of calcium carbonate (Flinn Catalog Nos. C0347, C0012, C0013, and C0014) and 6 Molar hydrochloric acid (Flinn Catalog No. H0033) will produce approximately 6 liters of CO2 at room temperature and atmospheric pressure. A drying tube should be a part of the generation apparatus.

Cans—Great Friends
Flinn Scientific packages calcium and other reactive metals in metal cans. Why? Because the package (i.e., the can), is the most protective container economically available to hold reac- tive substances. When you have to deal with chemicals that are unusually hazardous, consider using plastic bags and outer cans to provide additional protection for these “devils.” Put your bottle into a bag and then into a can. See Flinn Chem-Saf TM Bags and Saf-StorTM Cans on page 122.
 HAZARD ALERT: Moderately toxic by ingestion and inhalation. Skin irritant.
