Which of these acids would be considered a strong acid
A)one with a dissociation constant (K) = 0.05
B)one with a dissociation constant (K) = 0.10
C)one with a dissociation constant (K) = 0.47
D)one with a dissociation constant (K) = 0.99

Question

Quizplus · Accepted Answer

A strong acid has a high dissociation constant, indicating that it fully dissociates in water to produce a significant amount of H+ ions. A dissociation constant (K) of 0.99 indicates that nearly all of the acid molecules dissociate into H+ ions when dissolved in water, making it a strong acid. The values for A, B, and C are too low to be considered strong acids.
