Percent ionization Percent ionization for a weak acid (HA) is determined by the following formula: Percent ionization = [HA] ionized/[HA] initial times 100% For strong acids, ionization is nearly complete (100%) at most concentrations. However, for weak acids, the percent ionization changes significantly with concentration. The more diluted the acid is, the greater percent ionization. A certain weak acid, HA, has a K_a value of 9.9 times 10^-7. Calculate the percent ionization of HA in a 0.10 M solution. Express your answer as a percent using two significant figures. Calculate the percent ionization of HA in a 0.010 M solution. Express your answer as a percent using two significant figures.
