One of our TAs caught a mistake in EOC exercise 17.101.  It supposedly gives
the pKa values for phosphoric acid.  They are actually the Ka values.

Hi Dr. Zellmer,

I think I caught a mistake in the textbook, and I don't think you have sent a correction to the students. For question 17.101, it lists the K_a values for phosphoric acid, rather than the pK_a values as it states.

I've attached a screenshot of the question from the text.

Best,
Paul Blasiman
