Few Q's

  1. Mar 27, 2005 #1
    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.
