Chemistry-pH problem

posted by .

If a weak acid has a dissociation constant of 6.4 x 10(-6), what is the pH of a solution of this acid in 0.10 molar concentration?

  • Chemistry-pH problem -

    ..........HA ==> H^+ + A^-
    initial...0.1....0......0
    change....-x....+x......+x
    final.....0.1-x...+x.....+x

    Ka = (H^+)(A^-)/(HA)
    Substitute into Ka expression from ICE chart above and solve for (H^+), then convert to pH.
