Flashcards in Topic 8- Group 7 Elements Part 2 Deck (2)
How do halide ions become halogens?
What is this linked to?
What does it mean the larger the halide ion?
What is the reducing power like of halides?
What is the equation for the reaction of sodium chloride with concentrated sulfuric acid?
What type of fumes are produced?
What is this reaction not?
What is the chloride ion too weak to do?
Halide ions lose electrons to become halogens
Linked to size
The more easily it loses an electron
Increased reducing power as you go down the group
NaCl (s) + H2SO4 (l) ---> NaHSO4 (s) + HCL (g)
Misty white fumes produced
Not a redox reaction
Chloride ion is too weak as a reducing agent to reduce the sulfur in sulfuric acid.
