A Part A Determine [OH] of a solution that is 0.110 M M in F. (K₂ for HF is 6.8 × 10−4.) Express your answer in molarity to two significant figures. ΜΕ ΑΣΦ [OH-] = Submit Request Answer Part B Complete previous part(s) 0 ? M
This is a question for a lab about the standardization of an acid and base. In the lab, we used the weight of KHP to calculate the moles of NaOH and the molarity of NaOH( KHP and NaOH have a 1;1 mole ratio in the reaction). Then, we used the molarity of NaOH to calculate the molarity of HCl. If you recorded the weight of the KHP incorrectly, the value was too low, how would this effect the molarity of the HCl you calculate? I think the calculated molarity of HCl would be lower than what it should be. I just want to double check

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?
Thank you for your time and help!!
