Question

2.Why do we need sulphuric acid in concentrated condition for the lab preparation of HCl?​

Answer 1

Answer:

H2SO4 has dehydrating properties, so it can not only function as an acid, but also as a dehydrating agent in the synthesis of other acids. Most of the chlorides and nitrates are freely soluble in water, so that there is one additional byproduct to be separated and removed, if you use HCl or HNO3 as the acid.
