Which of the following solutions contains the strongest acid? A)5.00 M HCN (K_a = 6.2 $\times$ 10^-¹⁰) B)3.50 M H₂C₆H₆O₆ (K_a1 = 7.9 $\times$10^-⁵,K_a2 = 1.6 $\times$ 10^-¹²). C)2.50 M HC₂H₃O₂ (K_a = 1.8 $\times$ 10^-⁵) D)4.00 M HOCl (K_a = 3.5 $\times$ 10^-⁸) E)1.00 M HF (K_a = 7.2 $\times$ 10^-⁴)

Question

Quizplus · Accepted Answer

To determine the strongest acid, we need to look at the values of the acid dissociation constants (Ka) for each solution. The lower the value of Ka, the stronger the acid.

Of the given solutions, HF has the lowest Ka value (7.2 x 10^-4), indicating it is the strongest acid. Therefore, the best choice is E.
