Resumo de Recurso
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
Sodium fluoride
steamy fumes of hydrogen fluoride are seen
fluoride ion is an even weaker reducing agent than the chloride ion.
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
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
