Using the ionization constants found at https://sites.google.com/site/chempendix/ionization, calculate the overall equilibrium constant, Koverall, for the following reaction:
HCN(aq)+SO3^2-(aq) --><-- CN^-(aq)+HSO3^-(aq)
HCN H+ + CN- KaHCN = 3.5 x10-4
SO32- + H+ HSO3- Ka SO3- = 1/K2 = 1/6.3x10-8 = 1.6 x107
------------------------------------------------------------------
HCN + SO32- CN- + HSO3- Kt = KaHCN x KaSO3-
Kt =( 3.5 x10-4 )/(6.3x10-8) = 5.6 x 103
