Which factor do we use to determine the stronger acid when comparing the strengths of two weak acids?
A) the formula weights of the acids
B) the numbers of protons that the acids can lose
C) the values of the acid dissociation constant
D) none of these

Question

Quizplus · Accepted Answer

The strength of a weak acid is determined by its acid dissociation constant (Ka) value. The higher the Ka value, the stronger the acid. Therefore, to compare the strengths of two weak acids, we would look at their respective Ka values and choose the one with the higher value as the stronger acid.
