Acid Eaters

The grocer is acting strangely when Jeremiah walks in - he is frantic, pouring buckets of water on his face, into his mouth, and all down his front. "Gahdamb id herts!" he screams, tears flowing down his face. "Jeremiah," his son says, "we're so glad you're here! We imported this vinegar, and they sent us some sort of concentrate! My father tried it on his salad, and I'm afraid he'll never be the same."

"Oh my," Jeremiah mumbles as he reads the Italian labels. "Oh my, indeed. The concentration of this acetum is 5.69M. That is indeed dangerous. It says here the Ka = 1.76 x 10-5."

"What's that mean?"

"It means you should call the apothecary, and tell them your father needs help now! This solution is very acidic!"

How acidic was that salad dressing?
