For a week acid whose ionization constant is 1.75 x 10(-5), the pH of its solution is 3.0. Determine its degree of ionization and its percent ionization.

• chemistry -

HA ==> H^+ + A^-
Ka = (H^+)A^-)/(HA)
Set up an ICE chart and solve for (HA). Then

%ion = [H^+)/(HA)]*100 = ?
degree ion = %ion/100.
