In deciding which of two acids is the stronger,one must know:
A)the concentration of each acid solution
B)the pH of each acid solution
C)the equilibrium constant of each acid
D)all of the above
E)both A and C must be known

Question

Quizplus · Accepted Answer

The strength of an acid is determined by its ability to donate a proton (H+). This ability is measured by the acid dissociation constant, Ka, which is a measure of the extent to which the acid dissociates in solution. Therefore, knowledge of the equilibrium constant for each acid is necessary to determine which one is stronger. The concentration of each acid would only be relevant if comparing two solutions of the same acid at different concentrations, and the pH is influenced by both the concentration and the strength of the acid, making it a less reliable indicator of acid strength.
