To summarize: Ka * Kb is equivalent to adding the fresh new acidic and you may ft responses together with her, which results in a websites picture of autoionization out-of liquid. It is really not an excellent neutralization/acid-ft reaction, however, I believe the fresh new Kw = Ka * Kb was an analytical family made to facilitate calculations.
The relationship between Ka and you can Kb from the 25? having good conjugate acid base couples is actually B) Ka ? Kb = step one ? 10-14.
To possess an aqueous services regarding a faltering acid, the dissociation constant is named this new acid ionization constant (Ka). Similarly, the newest balance constant with the reaction of a failing legs that have water ‘s the legs ionization ongoing (Kb). For any conjugate acid–base couple, KaKb=Kw.
