Kb is for bases
So, HSO3- should act as base.
It should accept H+
HSO3- after accepting H+ forms H2SO3
So, the equation should be:
HSO3-(aq) + H2O(l) <—> H2SO3(aq) + OH-(aq)

The degree to which a weak base dissociates is given by the base-ionization constant, Kb. For the generic weak base, B B(aq)+H2O(l)⇌BH+(aq)+OH−(aq) this constant is given by Kb=[BH+][OH−][B] Strong bases will have a higher Kb value. Similarly, strong bases will have a higher percent ionization value. Percent ionization=[OH−] equilibrium[B] initial×100% Strong bases, for which Kb is very large, ionize completely (100%). For weak bases, the percent ionization changes with concentration. The more dilute the solution, the greater the percent ionization....
