Halogens
- Reactions with Iron
- Reaction equation for fluorine
- Iron+Fluorine-----> Iron(III)fluoride
- 2Fe + 3F2 --------> 2FeF3
- Displacement reactions
- A more reactive halogen can
displace a less reactive one in a
solution of its own salt
- Chlorine+Sodium Bromide --------> Bromine + Sodium chloride
- Cl2 + 2NaBr -----> Br2 + 2NaCl
- Silver Nitrate Test
- Halide ions can be
identified by their reactions
with silver nitrate
- Chloride, bromide and iodide can be
identified by their percipitates with silver
nitrate
- White silver chloride
- Cream silver bromide
- Yellow silver iodide
- Ag+ and Cl- > AgCl
- Important reaction takes place when
the two solutions react is the one
between the silver ions and the
chloride ions
