WebJun 1, 2015 · A good approximation for the pH can be found in this paper, as shown here: [ H X 3 O X +] = K a ∗ K w K a ∗ K b where K a is for C X 5 H X 5 N H X + and K b is for F X −. This leads to [ H X 3 O X +] = 4.85 ∗ 10 − 5 → p K a = 4.314 WebpKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be understood only if their pKa values are known.

HF is diatomic in the gas-phase. As a liquid, HF forms relatively strong hydrogen bonds, hence its relatively high boiling point. Solid HF consists of zig-zag chains of HF molecules. The HF molecules, with a short covalent H–F bond of 95 pm length, are linked to neighboring molecules by intermolecular H–F distances of 155 pm. Liquid HF also consists of chains of HF molecules, but the chains are shorter, consisting on average of only five or six molecules. http://clas.sa.ucsb.edu/staff/Resource%20Folder/Chem109ABC/Acid,%20Base%20Strength/Table%20of%20Acids%20w%20Kas%20and%20pKas.pdf cpt rank imageWebCalculate the pH of a 0.1 M HF solution.
