Question

ASSERTION
Reaction of liquor ammonia with nitric acid is a neutralization reaction.
REASON
Ammonia in the gaseous form or in aqueous solution as ammonium hydroxide neutralizes the nitric acid forming the respective ammonium salts.
A.Both Assertion and Reason are correct and Reason is the correct explanation tor Assertion
B.Both Assertion and Reason are correct but Reason is not the correct explanation tor Assertion
C.Assertion is correct but Reason is incorrect
D.Both Assertion and Reason are incorrect

Answer 1

Hint: The liquor ammonia is a solution of the ammonia in water, which can be reacted as a base and the nitric acid is an acid which on reaction with the base will produce salt and water as the products .It is one of the well known reactions.

Complete answer:
Ammonia is a molecule made up of one atom of nitrogen and three atoms of hydrogen. Now, when we prepare a saturated solution of ammonia gas with water it results in forming liquor ammonia, when ammonia reacts with water it produces a coordinate bond between nitrogen of ammonia and hydrogen of water molecule which results in formation of ammonium ion \[N{H_4}^ + \] and hydroxide ion $ O{H^ - } $ which are joined together with an electrostatic force by the charge generated on them i.e.
   $ N{H_4}^ + + O{H^ - } \to N{H_4}OH $
Which is known as ammonium hydroxide and it is a base, because it contains an hydroxide ion.
Now we know that when an acid is reacted with a base they result in the formation of salt and water which is popularly known as neutralisation reaction.
Now when nitric acid is reacted with liquor ammonia which is a base, undergoes the above type of reaction i.e. neutralisation reaction by producing a salt ammonium nitrate $ [(N{H_4})N{O_3}] $ and water $ {H_2}O $ .
Therefore we can say that both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

The correct answer is option. A

Note:
The Acid are the substances which gain an electron, it can be also viewed in a point that they lose a proton. On the other hand bases are quite opposite, they tend to lose an electron and gain a proton.
