8. Nitrogen:
Nitrogen gas is generally inert.
It is a colorless gas.
It has no Taste.
Melting point -210° C
Boiling point -196° C
9. Oxygen
Oxygen exists in all three forms - liquid, solid, and gas.
oxygen gas is colourless,
Tasteless.
Boiling point -182.96°C
Melting point -218.4°C.
10. Carbon Dioxide
Carbon dioxide is a colourless gas.
It is soluble in water .
Melting Point : -55.6 degC
Boiling Point : -78.5 degC
Density : 1.977
12. Nitrogen
The color of indicators is not affected by the Nitrogen.
Nitrogen can combine with other elements .
At high temperature or low temperature nitrogen can
form compounds.
13. Oxygen
it supports combustion.
Oxygen also combines with elements
at room temperature.
Oxygen also reacts with many
compounds.
14. Carbon Dioxide
Carbon dioxide is a linear covalent molecule.
Carbon dioxide is an acidic oxide and reacts with water
to give carbonic acid.
CO2 + H2O ==> H2CO3
15. Uses of pharmaceutical gas
Nitrogen:
Nitrogen is used for
Inerting
Lyophilisation
Drying
Liquid phase transfer
Oxygen
Oxygen is Used for
Chemical synthesis
Low temperature storage
Cyro condensation of waste gases
In fermentation
16. Ozone :
Used in chemical synthesis
Uses in cyro grinding
Low temperature storage
Carbon Dioxide :
It is used for
Inerting
Chemical synthesis
Extration
Transportation of products
17. Medicinal Gas
Medical gases fall the definition of drugs
and such must be treated as
pharmaceutical products
24. Helium
It is less soluble in water than any
other gas.
It is non toxic.
It is non-flammable
25. Nitrous Oxide
It is highly soluble in alcohol, ether, oils, and
sulfuric acid.
By heating ammonium nitrate, it will
decompose into nitrous oxide and water vapor
(NH4NO3 (s) → 2 H2O (g) + N2O (g)).
26. Hydrogen:
This gas is used in chemical synthesis and
biochemistry.
Ammonia:
This gas is used in chemical synthesis and
biochemistry.
Nitrous Oxide :Used as gas propeilant for aerosois
packaging
27. Uses of medicinal gas
Carbon dioxide :
Carbon dioxide in liquid phase provides temperatures of
down to -76.C and can therefore
It can be used for cryotherapy for local analgesia.
Helium :
Liquid helium is used to cool the magnets.
It also used in modern Magnetic Resonanace.
28. Nitrogen : It is used for
cryobiology
crytherapy.
Nitrous oxide :
N2O is used for introduction and maintenance of
inhalational anesthesia in combination with other drugs
such as volatile compounds,anesthetics,muscle relaxants
analgesic compouns and others.
Oxygen :
As oxygen is essential for life.Therefore oxygen is given for
treatment and prevention of a variety of cardiac pulmonary
and other diseases.
