APFIVE Relationship Between Ka Kb and Kw
Which equation correctly describes the relationship between the acid ionization constant, $$K_a$$, and the base ionization constant, $$K_b$$, for a conjugate acid-base pair?
A
$$K_a + K_b = K_w$$
B
$$K_a \times K_b = K_w$$
C
$$K_a - K_b = K_w$$
D
$$K_a / K_b = K_w$$
