Use activity coefficients to find the concentration of hydrogen
ions in a solution of 75.0 mM butanoic acid (C3H7COOH) and 0.05 M
NaCl. The ionization constant of butanoic acid is Ka = 1.52 × 10-5.
Take the size of C3H7COO– to be 500 pm.
What is the pH of this solution? Include activity coefficients in
your calculation.
What is the fraction of dissociation of butanoic acid in this
solution?
