Calculate the degree of ionization of acetic acid in solution 1. The degree of ionization of an acid = [H3O+]/[HA] where [H3O+] is the equilibrium concentration and [HA] is the original concentration of of the acid . [H3O+] can be determined from the measured of pH.
Solution 1. 20.0 mL of 0.1 M HC2H3O2 Measured pH 2.70.
