Which one of the following is a true statement? A)The stronger the acid,the larger is its pK_a. B)The conjugate base of a strong acid is a strong base. C)Acid-base reactions always favor the formation of the stronger acid and the stronger base. D)Strong acids can have negative pK_avalues. E)Hydrogen need not be present in the molecular formula of a Bronsted-Lowry acid.

Question

Quizplus · Accepted Answer

Strong acids can have negative pK_a values because pK_a is the negative logarithm of the acid dissociation constant (K_a), and strong acids dissociate completely in solution, resulting in a large K_a and thus a negative pK_a.
