Mystery gas. Is the gas
H2, O2,
CO2, or
air?
Percent Composition of CaCO3 in Tums antacid
Carbonated Beverages — Priestley’s Soda-water
Molar Mass - remarkably accurate results!
Limiting Reagent Magnesium + HCl(aq)
Barometric Pressure without a barometer
All gases.
Preparation instructions for many interesting gases with
about ten experiments and classroom demonstrations for
each. Gases include NO, NO2,
SO2, C2H2,
O3, NH3,
Cl2, H2S
and ten others.

Left: Upper syringe had contained colorless NO(g), but as O2(g) is added from the lower syringe, NO2(g) is instantly formed. Right: Underwater fireworks result when Cl2(g) and C2H2(g) are combined in close proximity underwater.

Why Microscale Gas Chemistry?
| • It's fun and easy! Easy to
learn how. Gases ready in 5 minutes! • Great labs! Great demos! Students enjoy making gases. • It's visual! Best way to 'see' a gas is to watch it being produced. • It's microscale in terms of quantities, but large enough to see - 60 mL. • It's inexpensive. A syringe of CO2 costs less than 1 cent to produce. • It's green - little or no chemical wastes. |

Our Gas Reaction
Catalyst Tube can be used to demonstrate a variety
of gas phase chemical reactions. The catalyst
contains a layer of disbursed palladium atoms on a
ceramic material and enclosed within a glass housing
as per the figure. Hydrogenation of alkenes occurs
at very temperatures (even < 0 deg C). A
wonderful classroom demonstration shows how a
catalytic converter works by transforming CH4
(or any hydrocarbon) + NO2 (the
reddish mixture in the left syringe below) into N2
+ H2O + CO2 (right
syringe - condensation droplets of water
are often noticed in right syringe).
Gas Bags
For classroom use,
gases can be prepared and stored in sealable plastic
food bags equipped with a dispensing tube.
Mini-Ozone Generator
Ozone is generated
for in situ use. The Mini-Ozone generator
produces 800 nanomole/minute. Safe and easy to
use. Off the shelf classroom demo that
anyone can build.
