Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Solutions of HF are colourless, acidic and highly corrosive. It is used to make most. The acid dissociation constant of HF is Ka=6.8×10?4 K a = 6.8 × 10 ? 4. Let us.. See full answer below. Become a member and. What is the Ka of HF if a 2.0 M solution of HF has a pH of 1.42? 60380) (46480 2 – (032) 1.962 pH = 142 = -log [HT] 7.36X10 [H*] -0380M Ka CH][F].. of a solution that is 0.25 M HF and 0.10 M NaF. Also, predict if these concentrations are appropriate to make a buffer solution. (5 pts). Ka = 3.5 x 10.Calculate the pH of a solution that contains 1.00 M HF (Ka = 7.2 x 10-4). Also calculate the concentrations of the Fluoride ions at equilibrium. Explanation.

## pka of hf

HCN pKa = 9.2 and HF pKa = 3.2, though I don’t know what this tells me other than that HF is a stronger acid than HCN.This is a buffer solution composed of hydrofluoric acid (weak acid) and fluoride anion (weak conjugate base from sodium fluoride) according to the..Fluorine has the most strongly ionic bond of the series. In terms of raw bond strength, the H-F bond is 30% stronger than the next strongest, HCl. When these. Hydrogen Halides. Hydrogen Fluoride (HF). m.p. -83.1oC, b.p. 19.9oC. pKa (aq) 3.17. r(H-F) = 0.92 Å dipole moment = 1.8D. Hydrogen Chloride (HCl).Because HF is a relatively weak acid (pKa 3.8), it is largely nonionized and can penetrate cell membranes easily. During deep tissue penetration,
