Properties of Oxygen
Safety: Waste:
Be cautious and always wear your safety Remaining yeast and hydrogen peroxide slurry
goggles!!! Spilled water can be a slipping can be disposed of down the drain in a stream of
hazard. If gases are generated inappropria water.
Leftover waste from the magnesium ribbon and

wastebasket.
Materials:
3% hydrogen peroxide (H2O2) solution
activated yeast
large Erlenmeyer filter flask
tely in a closed system, they can cause five wide-mouth bottles
explosions. Combustion reactions generate four glass plates
a lot of heat and can catch loose hair and pneumatic trough
clothing on fire if not carefully controlled. 1 hole stopper equipped with a thistle tube
Always be careful and considerate of other rubber or silicon tubing
people working around you. stopwatch or timer
wooden splints
Hydrogen Peroxide (H2O2), 3% solution candle
can cause serious eye damage or irritation sulfur
and skin irritation. steel wool
magnesium ribbon
Paraffin wax smoke can be a lung irritant. utility clamp
stand
Sulfur dioxide (the product of burning deflagration spoon
sulfur) is a highly acidic gas and causes crucible tongs
severe irritation upon inhalation. It can also small beaker
trigger asthma attacks. It should only be medium beaker
produced in a properly ventilated fume
hood.
Magnesium emits ultraviolet light at a
dangerous intensity when burned, which can
cause blindness if viewed directly.
Black smoke from burning wood or candles
can be an inhalation irritant.
Unextinguished embers on wooden splints
and steel wool can light fires when placed in
the wastebasket.

Procedure:
Part I. Generating and Collecting Oxygen Gas:
1. Obtain the following equipment from the supply cart: 250 mL Erlenmeyer flask, stopper +
thistle tube + rubber tubing apparatus, five wide mouth bottles, four glass cover plates.
2. Obtain the pneumatic trough from your drawer.
3. Connect the bottom hole of the pneumatic trough to a flexible rubber or silicone tube, and
thread it through the hole in the pneumatic trough so water does not run out of it. Fill the
pneumatic trough to approximately 1/2 in. above the plastic shelf.
4. Fill four of the wide-mouth bottles to the brim with water. Gently slide a glass plate over the
mouth of each bottle.
5. While holding the glass plate in place, carefully invert a bottle and lower it into the water in
the pneumatic trough. Remove the glass plate while the mouth of the bottle is under the
water. Place the glass plate aside on a paper towel. Repeat for all four bottles. If not all the
bottles fit in the trough, bottles can also be placed on the shelf so long as the mouth of the
bottle does not come out of the water.
Include a drawing or photograph of your setup in this space:
6. Add a quarter sized amount of activated yeast to the Erlenmeyer filter flask, followed by
about 25 mL of tap water. If necessary, add more yeast so that it is a slurry-like thickness
(thick, but still fluid).
7. Connect the tubing from the pneumatic trough to the filter flask through the side.
8. Insert the rubber stopper into the filter flask such that the bottom of the thistle tube is
submerged in the slurry, but not touching the bottom of the flask.
9. Stabilize the filter flask with a utility clamp attached to a ring stand.
10. Slide the first oxygen collecting bottle (which is full of water) over the hole in the bottom of
the trough.
