Which of the following is an untrue statement? A)The % dissociation of a weak acid increases with increasing dilution of the acid solution. B)The stronger an acid,the weaker its conjugate base. C)The larger the value of K_a for an acid,the smaller the value of its pK_a. D)Comparison of the acidity of strong acids in solution requires the use of a solvent less basic than water. E)The stronger the acid,the more positive the value of $\Delta$Gº for the dissociation.

Question

Quizplus · Accepted Answer

The correct statement is that the stronger the acid, the more negative (not positive) the value of ΔGº for the dissociation. This is because a negative ΔGº indicates a spontaneous process, which is consistent with the behavior of strong acids dissociating in solution.
