Solution

For the preparation of Hydrogen chloride gas, Sulfuric acid and Sodium chloride are used.
Sulfuric acid and Sodium chloride react in different ways at different temperatures.
Sodium sulfate is formed as a byproduct in this reaction that takes place at a temperature above $200 ° C$ .
The reaction that takes place at a temperature above $200 ° C$ is,
$\underset{S o d i u m c h l o r i d e}{2 N a C l (s)} + \underset{S u l f u r i c a c i d}{H_{2} S O_{4}} (a q) \to \underset{S o d i u m s u l f a t e}{N a_{2} S O_{4} (s)} + \underset{H y d r o g e n c h l o r i d e}{H C l (g)}$
