A certain monoprotic weak acid with Ka = 6.7 × 10-8 can be used in various industrial processes, but is no longer used in chemistry teaching labs because it tends to explode when it gets old. (a) What is the [H+] for a 0.558 M aqueous solution of this acid and (b) what is its pH?

PLEASE HELP!!

  1. ...........HA ==> H^+ + A^-
    begin....0.558M...0.....0
    change.....-x......x.....x
    final...0.558-x....x.....x

    Ka = (H^+))A^-)/(HA)
    Substitute the ICE chart values I made into the Ka expession and solve for H^+.
    b) pH = -log(H^+)
