(i) What is the type of salt formed when the reactants are heated at a suitable temperature for the preparation of Nitric acid?

Solution

Nitric acid is prepared by the reaction of Sulfuric acid and Potassium nitrate.
Nitric acid preparation at a suitable temperature results in the formation of a salt and is Potassium hydrogen sulfate.
The chemical equation for its preparation is,
$\underset{P o t a s s i u m n i t r a t e}{K N O_{3}} + \underset{S u l f u r i c a c i d}{H_{2} S O_{4}} \to \underset{P o t a s s i u m h y d r o g e n s u l f a t e}{K H S O_{4}} + \underset{N i t r i c a c i d}{H N O_{3}}$
So Potassium hydrogen sulfate salt is formed during Nitric acid preparation.
