Abstract—Ion exchange equilibrium constant (K) for Cl
/Br
and Cl
/
system was studied at different
temperatures from 30 to 45
C. For both uni-univalent and uni-bivalent exchange systems, the value of K
increases with rise in temperature i.e., from 1.16 at 30
C to 2.95 at 45
C for Cl
/Br
system and 19.5 at 30
C
to 30.0 at 45
C for Cl
/
system indicating the endothermic ion exchange reaction. The difference in K
values at the same temperature for the two was related to the ionic charge of exchangeable ions in the solution.
