Given that Ka for HCN is 6.2 × 10-10 at 25°c, what is the value of Kb for CN- at 25°c?
Given that Kb for NH3 is 1.8 × 10-5 at 25°c, what is the value of Ka for NH4+ at 25°c?
Ka is an acid dissociation constant ,it is a measure of the degree of ionization that the acid has.
Kb is a base dissociation constant. It describes the ionization rate that the base has.
Dissociation constant is a kind of equilibrium constant, which reflects the concentration of compounds and the reaction that follows dissociation. The dissociation value depends on the dissociation process of the substance. Strong electrolytes have a large value of dissociation constant , while weak electrolytes, which dissociate in part, are of low value for dissociation constant.
