# What is the percent ionization for each of the following acids?

a. 0.022 M HClO2 solution of pH= 3.88

Answer obtained: .60%

pH = 10^(-3.88) = 1.32 x 10^-4

% ionization= [H+] formed divided by

MHA (original acid concent) x 100

= (1.32x10^-4)/0.022 x 100

= .60%

b. 0.0027 M HClO2 solution of pH=4.70

Answer obtained from solving: .44%

pH = 10^(-4.70) = 1.20 x 10^-5

% ionization

= (1.20x1-^-5)/0.0027 x 100

= .44%
