Calculate the percent ionization in a 0.1M solution of hydrofluoric acid (Ka=3.53*10^-4)
HF <-------> H+ + F-
Initial 0.1 0 0
Change - x +x +x
Equilibrium (0.1-x) x x
Ka = 3.53 * 10-4 = x. x / (0.1-x)
x = 0.005767
Percent ionization = ( Ionized concentration / unionizedconcentration ) * 100
= ( 0.005767 / 0.1) * 100
=5.767 %
