The reactions of
sodium halides
with concentrated
sulfuric acid
- Sodium chloride
- steamy fumes of hydrogen
chloride are seen
- solid sodium
hydrogensulfate is
evolved
- NaCl (s) + H2SO4 (l)
--> NaHSO4 (s) +
HCl (g)
- NOT a redox reaction as the oxidation state has
not changed as the chlorine ion is too weak a
reducing agent
- acid-base reaction
- steamy fumes of hydrogen
chloride are seen
- Sodium fluoride
- steamy fumes of hydrogen fluoride are seen
- fluoride ion is an even weaker reducing agent than the chloride ion.
- steamy fumes of hydrogen fluoride are seen
- Sodium bromide
- steamy fumes of hydrogen
bromide are seen
- brown fumes of bromine are seen
- colourless sulfur dioxide is also formed
- because the bromide ions are strong enough
reducing agents to reduce the sulfuric acid to sulfur
dioxide
- because the bromide ions are strong enough
reducing agents to reduce the sulfuric acid to sulfur
dioxide
- steamy fumes of hydrogen
bromide are seen
- Sodium iodide
- steamy fumes of hydrogen iodide are seen
- black solid of iodine forms
- bad egg smell of hydrogen sulfide gas
- yellow solid sulfur may occur
- colourless sulfur dioxide is
also evolved
- steamy fumes of hydrogen iodide are seen
