Nitric Acid Questions and Answers
What was nitric acid initially called - answer Aqua Fortis

Who called nitric acid "Aqua Fortis "and why - answer Alchemists in the eighth
century because of its corrosive nature on many medals

Who prepared nitric acid, when and how - answer Glauber in 1658 by distilling nitre
(KNO3) with concentrated sulphuric acid

Who determines the composition of nitric acid and when - answer Cavendish in 1784

Where does nitric acid occur in the free State - answer During lightning discharge,
nitrogen in the atmosphere reacts with the oxygen to form nitric oxide which is further
oxidised to nitrogen dioxide. Nitrogen dioxide dissolve in the presence of oxygen
forming nitric acid which falls to the earth along with the rain water which may form
soluble nitrates.

What is atmospheric nitrogen fixation - answer Conversion of free atmospheric
nitrogen into useful nitrogen is compounds in the soil

Give the reaction of nitrogen and oxygen - answer N2 + O2 --> 2NO (lightning
discharge)

Give the reaction of nitric oxide and oxygeb - answer 2NO + O2 --> 2NO2

Give the reaction of nitrogen dioxide and water in presence of oxygen - answer
4NO2 +2H2O +O2 --> 4HNO3

Give the reaction of nitric acid and mineral carbonates - answer 2HNO3 + CaCO3 --
> Ca(NO3)2 + H2O + CO2

Where does nitric acid occur in the combined state - answer In its salts in minerals

What is chile saltpetre - answer NaNO3

What is Bengal saltpetre - answer KNO3

What is nitre - answer KNO3

What is the lab preparation of nitric acid - answer KNO3 + H2SO4 (conc) --<200C-->
KHSO4 + HNO3

, Why is the apparatus used for lab preparation of nitric acid composed of glass - answer
Because nitric acid papers are highly corrosive and attack rubber, cork, et cetera

Why is concentrated sulphuric acid used in the lab preparation of nitric acid - answer
It is a strong nonvolatile acid capable of displacing the more volatile nitric acid

What is the molar ratio of the reactants in the lab preparation of nitric acid and why -
answer 1:1 since even though sulphuric acid is dibasic an acid salt is formed so only
half of the hydrogen of the acid is used up

Why does the lab preparation of nitric acid take place at temperature is less than or
around 200°C - answer Higher temperatures are not used because they cause
damage to the glass apparatus, for the decomposition of the nitric acid, formation of a
hard residual crust of the corresponding sulphate which cannot be easily removed

Why does the colour of pure nitric acid differ from the colour of nitric acid obtained in the
laboratory - answer Sure nitric acid is colourless while the nitric acid obtained in the
lab is slightly yellowish-brown due to decomposition of the acid, which is negligible out
for dinner temperatures but substantial at high-temperature is.

Give the reaction of the composition of nitric acid - answer 4HNO3 --> 4NO2 + 2H2O
+ O2

How can the yellow brown tinge in the acid be removed - answer 1.bubbling of air or
carbon dioxide in which drives out the reddish brown nitrogen dioxide gas from the
warm acid and oxidises nitrogen dioxide to nitric acid
2.dilutional with water which causes dissolution of the nitrogen dioxide gas

What is the name of the industrial preparation of nitric acid - answer Ostwald's
process

What are the three Chambers of Ostwald is process - answer 1.catalytic chamber
2.oxidation chamber
3.absorption tower

Which reaction takes place in the catalytic chamber - answer 4NH3 + 5O2 --> 4NO
+6H2O +21.5 kcal
(Pt catalyst, 700-800 C)

What are the reactants in Ostwald process - answer Pure dry ammonia, dry air

What is the optimum temperature for catalytic oxidation of ammonia to nitric acid -
answer 700 to 800°C

What is the catalyst of catalytic oxidation of ammonia to nitric oxide - answer
Platinum gauze
