How to Calculate Kb From Ka 
by Thierry Brunet in Education 

The Bronsted Lowry definition of an acid and a base is that an acid donates
hydrogen ions, whereas a base receives the hydrogen ions. The Kb is the
base dissociation constant, or the way in which the ions that compose the
base separate into their positive and negative components. The Ka is the
acid dissociation constant. The larger the value of Kb, the stronger the
base, and the larger the value o

Calculating the first dissociation constant (Ka1) requires several steps.
Concept applicability must be establishedKa1 makes sense only with
polyprotic (multiplehydrogen) acids. Once the polyprotic acid is
identified, consider the general Ka1 formula: Ka1 = [H+][HA]/[H2A]. Detail
and interpretation of this formula needs to be taken into account when
