I have the 4th edition of Tro Nivaldo's Chemistry: a Molecular Approach book and on page 731 the Ka value of HF is given as 6.8 x 10^-4, but in the solutions guide on bartleby for the end of chapter question chapter 17 question 33b, the HF values is 3.5 x 10^-4. Furthermore, google gives the Ka value of HF as 7.2 x 10^-4. Can you explain why I'm seeing all of these different values?
