..........HA --> H^+ + A^-
Initial.0.125....0......0
change....-x.....x......x
equil..0.125-x...x......x
Ka = (H^+)(A^-)/(HA)
Plug into the Ka expression and solve for x = (H^+).
Then % ion = [((H^+)/(0.125)]*100 = ?
Oh, ok! I was over thinking the problem!!! Plus a fever may not help with my problem solving abilities... Thank you!
