water contains bromide ions.
Chlorine is bubbled through sea water
to displace the less reactive bromine.
+ sodium bromide sodium chloride + bromine.
Cl2(g) + 2NaBr(aq) 2NaCl(aq) + Br2(aq)
The ionic equation for the reaction is
Cl2(g) + 2Br-(aq) 2Cl-(aq) + Br2(aq)
The more reactive
chlorine has taken an
the bromide ion, forming a chloride ion and bromine.
water is warmed and the
bromine is collected as
a gas from the surface of the water and condensed.
