During thunderstorm, rain water contains nitric acid. Explain with reactions. 

Write a balanced chemical equation for the laboratory preparation of nitric acid 

In the preparation of nitric acid from KNO3 concentrated hydrochloric acid is not used in place of concentrated sulphuric acid. Explain why?

Conc. Nitric acid prepared in laboratory is yellow in colour why? How is this colour removed?

Give reasons for the following:
In the laboratory preparation of nitric acid, the mixture of concentrated sulphuric acid and sodium nitrate should not be heated very strongly above 200°C. 

Nitric acid cannot be concentrated beyond 68% by the distillation of a dilute solution of `HNO_3` State the reason.  

What is passive iron? How is passivity removed? 

Name the products formed when:  

carbon and conc. Nitric acid is heated 

 

Name the products formed when: 

dilute HNO3 is added to copper.

Write balanced equations and name the products formed when:
Sodium hydrogen carbonate is added to nitric acid

Write balanced equations and name the products formed when: 

cupric oxide reacts with nitric acid 

Write balanced equations and name the products formed when: 

zinc reacts with dilute nitric acid

Write balanced equations and name the products formed when: 

concentrated nitric acid is heated

Correct the following, if required: 

`HNO_3` is strong reducing agent.  

Correct the following, if required: 

`NaNO_3` gives `Na_2` and `O_2` on heating.

Correct the following, if required: 

Constant boiling nitric acid contains 80% nitric acid by weight. 

Correct the following, if required: 

Nitric acid remains colourless even when exposed to light. 

Name: 

a nitrate of metal which on heating does not give nitrogen dioxide 

Name: 

a nitrate which on heating leaves no residue behind. 

Name: 

a metal nitrate which on heating is changed into metal oxide

Name: 

a metal nitrate which on heating is changed into metal 

Name: 

a solution which absorbs nitric oxide 

Name:

the oxide of nitrogen which turns brown on exposure to air. How is it prepared? 

Give the chemical name and formula of the substance formed as a brown ring in the test for nitrate radical. 

Mention three important uses of nitric acid. Give the property of nitric acid involved in the use. 

Choose the correct answer:

 The nitrate salt which does not give a mixture of NO2 and O2 on heating is: 

(1) `AgNO_3`  (2) `KNO_3`
(3) `Cu(NO_3)_2 ` (4)` Zn(NO_3)_2`

Choose the correct answer: 

The chemical used in the brown ring test is:
(1) `CuSO_4` (2)` FeSO_4`
(3) `Fe_2(SO_4)_3` (4) `N2O_5`

Explain with the help of a balanced equation, the brown ring test for nitric acid. 

why is freshly prepared ferrous sulphate solution used for testing the nitrate radical in the brown ring test?
