When a base (BOH) disociates in water the following equilibrium takes place:
[tex]BOH\rightleftarrows OH^-+B^+[/tex]Then the base dissociation constant (Kb) is expressed as:
[tex]Kb=\frac{[OH^-][B^+]}{[BOH]}[/tex]It is the product of the concentration of the products devided by the concentration of the reactant
