1. A solution of hydrofluoric acid contains 2.0g of HF per litre and has a pH of 2.2. What is the dissociation constant for HF? 2. The formation products is strongly favoured in this acid-bse system HX + B (to the -) <---- -----> HB + X(tothe-) a) identify the bases competing for the protons b) which base is tronger c) which is the weaker acid, HX or HB d) does the k for this system hav ea large or small value? e) how is the equilibrium affected by the addition of the soluble salt NaB? Thanks for the help.
