Abstract
Ion exchangers in chloride form were equilibriated with potassium
iodide and potassium bromide solutions of different concentrations
and at different temperatures from 30-45oC. The equilibrium
constant (K) values for both exchange reaction were observed to
increase with increase in temperature. However the equilibrium
constant (K) for Cl-/Br- exchange at 30°C was 1.16 which was less
than 16.70 for Cl-/I- exchange at the same temperature which was
due to difference in ionic size of iodide (2.20 Å) and bromide
(1.96 Å) ion exchanged.
