4. HISTORY
Nitric acid first descovered by Albert and Ramon Lull in the
13th century
Nitrogen compounds are well known in middle ages.
In olden days nitricacid called as aqua fortis.
Earlier nitric and hydrochloric acids known as aquaregia,which
has ability to dissolve gold.
From these things our elders came to know that nitricacid
have some useful applications in world.

5. PROPERTIES
PROPERTIES
Mol. Wt. : 63.03
MP: -42 oC
BP: 86 oC with decomposition
Completely miscible with water
Forms a constant boiling mixture at 11o oC and 760 mm of
Hg, which contains 68 wt.% HNO3.
Grades: Concentrated (95%), Fuming
( 86%), Redfuming( 95%with10 −
15%excessoxidesofnitrogen), nitrating(50 − 80%HNO3ˆa15 −
48%H2SO4)

6. METHODES OF PREPARATION
METHODES OF PREPARATION
NaNO3 + H2SO4 process
Ammonia oxidation process
N2 fixation from air (Wisconsin process)
Nitrogen fixation by nuclear fission fragments

9. CHALLENGES
NO formation at high temp but NO2 from No at low
temperatures
Reaction rate is directly proportional to: -Low temp -High
pressure (for catalyst ) -NO2 concentration in gaseous phase
Reaction kinetics is favored for high temperature and pressure,
good catalyst

10. APPLICATIONS
Precursor to organic nitrogen compounds
Nitric acid is used for making fertilizer such as ammonium
nitrate.
It can be used as cleaning agent

11. continue
Precursor
Nitric acid has been used as oxidizer in liquid fueled rockets.

12. safety
Nitric acid is higly corossive in nature.
will decompose the tissue such as skin,fat.
