E) both the concentration and the equilibrium constant of each acid.

Question

Quizplus · Accepted Answer

The strength of an acid is determined by its ability to donate protons, which is quantified by its equilibrium constant (Ka) for the dissociation reaction in water. The pH and concentration of an acid solution do not directly indicate the acid's inherent strength but rather its effect in a particular solution.
