In terms of strong acids, a large Ka value indicates what about the dissociation of that acid?

A large Ka value signifies that the acid dissociates extensively in solution, which leads to the conclusion that it is a strong acid. Ka, or the acid dissociation constant, quantifies the extent to which an acid can donate protons (H+ ions) to water, forming its conjugate base. When the Ka value is large, it indicates that a significant proportion of the acid molecules dissociate into hydronium ions (H3O+) and conjugate base. This strong dissociation results in an increase in H+ ion concentration in the solution, which is characteristic of strong acids.

In contrast, a small Ka would indicate weak acids that do not dissociate significantly, resulting in a lower concentration of H+ ions. Thus, a large Ka is directly linked to the strong acid behavior, confirming that such an acid dissociates more readily in solution, which aligns with the correct answer.
