gas fumes in moist air but H2S does not.
2. HCl
gas is not collected over water.
3. HCl
gas cannot be dried using quick lime.
4. In
the laboratory preparation of HCl, temperature is maintained below 2000C.
5. HCl
gas exposed to Ammonia gives white dense fumes.
6. Conc.
HNO3 is not used instead of Conc. Sulphuric acid in the preparation
