Laboratory preparation of Hydrogen Chloride Gas and Hydrochloric Acid.
Test for the gas using concentrated ammonia solution and moist UI paper.
Care: This must be carried out in a Fume Cupboard
Concentrated sulphuric acid is added to solid sodium chloride.
NaCl(s) + H2SO4(l) = NaHSO4(aq) + HCl(g)
Other relevant equations, referred to in the video, are:
HCl(g) + NH3(g) = NH4Cl(s)
The ammonium chloride forms as a gas that then cools and sublime to a solid
HCl(g) + H2O = H3O+ + Cl-
This positive ion is called a HYDROXONIUM ion. When hydrogen ions are formed in water they immediately pair up with water molecules to form this ion.
