Testing for chlorine halides using sulfuric acid Flashcards
1
Q
Chloride, bromide and iodide ions react with concentrated sulfuric acid to produce
A
toxic gases
2
Q
These reactions should therefore be carried out in a
A
fume cupboard
3
Q
The general reaction of the halide ions with concentrated sulfuric acid is:
where X is the halide ion
A
H2SO4(l) + X-(aq) → HX(g) + HSO4-(aq)
where X is the halide ion
4
Q
Reaction of chloride ions with concentrated sulfuric Acid
Concentrated sulfuric acid is dropwise added to sodium chloride crystals to produce
A
hydrogen chloride gas
5
Q
Concentrated sulfuric acid is dropwise added to sodium chloride crystals to produce hydrogen chloride gas
reaction
The HCl gas produced is seen as
A
H2SO4 (l) + NaCl (s) → HCl (g) + NaHSO4 (s)
white fumes
