Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). However, we know that for a weak acid and its conjugate base, the relationship of Ka to Kb is, (2) KaKb=Kw, where Kw = 10-14 is the dissociation constant of water, H2O H+ + OH- (if you are studying acid-base equilibria, it is a really good idea to memorize Kw !!
