How do you calculate Kb? Is it the recipricol of Ka?

Kb is the base dissociation constant, so the higher the value is, the stronger the base is. Kb multiplied by Ka should give Kw, the dissociation constant for water (at equilibrium). So, Kb = Kw/Ka.

Just like for Ka, Kb is calculated by this equation: [B+][OH-]/[BOH]. A lower Kb value indicates a stronger base.
