Problem

For a weak base B with base-dissociation constant

K_b

, what is the relationship between the acid-dissociation constant

K_a

of its conjugate acid

BH^+

and the ion-product constant of water

K_w

at 25 °C? a)

K_a = \sqrt{K_wK_b}

K_a = \dfrac{K_w}{K_b}

K_a = K_w\,K_b

K_a = \dfrac{K_b}{K_w}
